2021 Ducati Streetfighter V4 S Review | MC Commute

  • last year
Ducati’s Streetfighter V4 is easily one of the most—if not the most—aggressive high-performance naked bikes the world has seen. And it gets even more rowdy when bathed in accessories from the Ducati Performance catalog. Dripping in carbon fiber, magnesium, and titanium this $47,787.43 (as tested) V4 S is as wild as an accessorized production bike gets.

--

As usual, the highlight of this Ducati is the insane performance of its 1,103cc V-4 engine. From bottom to top, this engine has a powerband that feels like it came straight from satan’s workshop (good thing). And it’s even more vicious with the $5,541.15 handmade titanium Akrapovič exhaust and $3,548.65 dry clutch. If you’re a die-hard motorsport enthusiast, this is music to your ears.

There are a lot of neat-sounding and high-performance two- and four-wheeled vehicles out there, but nothing sounds as mean, nor accelerates as quickly as this Streetfighter—especially when you’re giving it the beans near its 15,000 rpm redline.

Yet, if you lug the engine at lower revs and short-shift it through the six-speed gearbox, the Streetfighter happily complies offering quasi-civilized manners. Miles per gallon figures in the high 30s are also possible if you stay off the pipe. Realistically however, expect around 30 mpg if you ride it like you’re supposed to.

The Öhlins semi-active suspension performs well and filters out the effects of worn pavement yet provides suitable road holding at lean with generous servings of throttle. We preferred the dynamic setting in its most aggressive suspension program.

A high-end electronics package allows for plenty of adjustability. The electronics have a wide range of adjustment allowing the rider to tweak the engine, traction control, and ABS character to their skill set. Advanced riders will especially appreciate the lofty performance barrier the electronics allow. For instance, the ABS programming in Level 3 (most restrictive) is at a higher level than some manufacturers’ setups on modern liter-class superbikes. Well done, Ducati.

A 5-inch color TFT display keeps tabs on it all. It’s a reasonably sharp-looking display, but it should be larger and the user interface remains well behind the competition. The menu navigation and switch gear are clunky and Ducati could learn a thing or two from Apple, BMW, and Yamaha...

00:00 Hey folks good morning and welcome to another episode of Motorcyclist MC
00:04 Commute. Today we're gonna be riding Ducati's 2021 Streetfighter V4S but
00:10 this isn't any ordinary Streetfighter V4S if that you can even say that. This
00:15 is a fully decked out Streetfighter with Ducati performance accessories to the
00:21 tune of almost $48,000. Whoa! Let's swing a leg over it and tell you what it's
00:26 like to ride. Alright folks here it is Ducati's 2021 Streetfighter V4 Dark
00:34 Stealth Project bike. This is Ducati's premier naked class bike. It came out as
00:44 an all-new model based on the Panigale V4 for the 2020 model year. Look at those
00:51 carbon fiber winglets. That's a $1,500 accessory. Look at those awesome folding
00:59 levers right there. That's another $1,500 for that lever, that lever, these turn
01:04 signals, and that awesome Rizoma twist-off fuel camp. Draped in carbon
01:11 fiber and magnesium. Yes those are forged magnesium wheels from Marchesini. Forged
01:18 magnesium wheels they weigh about one and a half pounds less than the forged
01:24 alloy wheels on the Streetfighter V4S. We also have the Akrapovic titanium
01:34 exhaust that drops eleven and a half pounds off the weight of this motorcycle.
01:38 Adds around 10 horsepower and wait till you guys hear the sound of this thing. It
01:44 is unbelievable. There's also a dry clutch conversion kit on the other side
01:50 of the bike. Yes Ducati was renowned for doing dry clutches in their old super
01:54 bikes and this thing has a dry clutch and oh my god is it totally awesome. We
02:00 also have this premium accessory seat. Ducati Performance. This bike is $47,000
02:09 nearly $48,000 when you add up the cost of the vehicle which is around
02:14 $25,000 and all the accessories. $48,000 for this bike. Is it worth it? Let's find
02:22 out. Alright folks a good old-fashioned mechanical key. Are you guys ready for
02:29 this? Listen to that dry clutch and Akrapovic titanium racing exhaust. Now
02:37 this is what a motorcycle is supposed to sound like.
02:44 Now the ergonomics package on the Streetfighter V4. Now that I've spent
02:51 some time on it I really like and appreciate this ergonomics package. These
02:57 motorcycles are good for older guys like myself who like to wail but kind of be
03:04 comfortable too and that's what the ergos on the Streetfighter V4 are all
03:10 about. The handlebar has a nice bend to it. It's not too narrow. It doesn't have too
03:19 much rearward sweep. The rise isn't too much. It's a very well engineered
03:25 handlebar. The rider's seat is about 0.7 inch taller than a standard
03:34 Streetfighter with this Ducati performance accessory seat. I love this
03:41 seat. It has a lot of padding. It is manufactured from a nice fabric. It has
03:48 a very nice appearance on it. The only maybe bad thing is this seat has got a
03:53 lot of grip to it so it's hard for me to move my my posterior around the cockpit
04:00 in the corners. You know if you're someone who likes to have a high grip
04:04 seat you're gonna like it but it's got a little bit too much grip. But I like how
04:09 tall it is. I like how thick and supportive and it's aesthetic. I'm also
04:14 big fan of these Ducati accessory rear sets that they've manufactured in
04:22 partnership with Rizoma. These foot controls allow for position adjustment.
04:29 Right now they are in the lowest setting which I like. This bike gives me a high
04:35 degree of comfort yet still has enough cornering clearance when I'm getting
04:41 some in on my favorite back road. Very comfortable ergonomics package on this
04:50 Streetfighter V4 S project bike. The only knock is if you're not a taller person
04:56 you might have a hard time touching the ground. The seat height on this bike is
05:01 right around 33 inches so it is a pretty tall motorcycle. But I'm tall I'm six
05:07 foot tall so I love it.
05:10 Now despite this motorcycle employing a dry clutch
05:18 clutch mechanism is actually very easy to use. This hydraulic assist makes it
05:25 easy to pull in the lever with two fingers. I like the clutch response. Now
05:31 back in the day when Ducati was using dry clutches on its super bikes the
05:36 clutch mechanism was, god they were just so, they were so vague feeling and had
05:43 such heavy clutch lever pull. This this dry clutch conversion is just it works
05:51 very well. I almost wonder why you'd ever want a wet clutch with based on just how
05:59 good this thing operates. Obviously the noise of this dry clutch you could never
06:04 pass sound and emission testing with this dry clutch just because it's so
06:12 loud. It's crazy loud but who cares I like the sound of it.
06:18 Now this Streetfighter V4 S is powered by Ducati's what's soon becoming
06:26 legendary 1103cc V4 engine. This is the engine they debuted debuted for the
06:33 2018 model year with the Panigale super bike. Now I love this engine I loved it
06:41 from the moment I twisted the throttle on it at Valencia. This thing is just
06:47 it's classic Ducati. It's got loads of character, loads of sound, and loads of
06:56 power. Basically what Ducati did is they took their L twin V twin concept and
07:04 multiplied it by two. So twice the power, twice the performance, twice the
07:10 character, and I really like this engine. Now that I've been starting to spend
07:16 some serious time on it what I really appreciate the most is how civilized
07:21 this engine can be. It's so civilized at lower RPMs it's just very impressive
07:28 how easy and mild-mannered the engine can be.
07:34 Of course when you're whaling on it near its 15,000 RPM redline that's when
07:41 things get really exciting but to have an engine to have a powertrain that's so
07:47 versatile that can give just an insane amount of power yet still have good
07:57 street manners and still be usable and still be relatively easy to ride that is
08:03 what's really impressive about this powertrain. Power is put back to the rear
08:12 tire via a six-speed transmission with up and down quick shifter and a chain
08:21 final drive. I love the electronic programming on this quick shifter. It
08:27 changes between each of the cogs very quickly. You just press on the lever you
08:32 don't have to use the clutch. Other electronic quick shifters sometimes have
08:39 delayed programming. This one's very immediate. It feels very racy
08:45 and the entire electronics package on this Ducati Streetfighter V4 is pretty
08:51 racy but we'll get to that in a minute.
08:57 Now this particular Streetfighter V4 S is rolling on Ducati's Marchesini forged
09:08 magnesium wheels. So the standard Streetfighter V4 comes with cast alloy
09:16 wheels. The V4 S comes with forged alloy wheels and this bike has forged
09:25 magnesium wheels and the wheels on this bike they're about one almost two pounds
09:33 lighter than the forged alloy wheels. And even though it's only two pounds it makes a big
09:40 difference. Now the standard V4 S weighs right around 439 pounds with a full 4.2
09:48 gallons of fuel. This Streetfighter V4 S project bike weighs right around 425
09:55 pounds. It's about 14 pounds less than the standard V4 S. And the way
10:05 Ducati got the weight savings on this bike is the active pocket exhaust that sheds
10:10 around 11 pounds. These wheels are another almost two pounds and then some
10:17 of the carbon fiber goodies. And this bike is crazy maneuverable, crazy
10:23 maneuverable for a 425 pound bike.
10:27 We spent some time riding this motorcycle on my favorite back road and
10:34 it's just insane how good this bike handles.
10:39 It turns quickly, it's relatively stable. The Ducati electronic suspension,
10:48 Ohlins semi-active suspension, it works really well.
10:55 Some of the funky mid-stroke weirdness I experienced with the 2020 V4 S, I don't
11:04 feel that with this setup. To be fair, this bike is rolling on Pirelli's
11:11 Diablo Supercorsa SPV3 tires versus the Diablo Rosso Corso 2 tires that the
11:21 standard Streetfighter V4 S rolls on.
11:26 But I'm really impressed with the suspension on this motorcycle.
11:32 Now the semi-active suspension automatically adjusts damping in real time
11:39 based on rider control input, i.e. brakes and throttle, and the dynamic of the
11:47 vehicle measured by the IMU. And what I like about this bike is it actually has
11:55 good compliance over bumps and over broken pavement. Ducati motorcycles,
12:03 sport motorcycles, have historically always had terrible ride quality over
12:08 bumps and terrible comfort in terms of suspension action on the street. But with
12:14 this DES, they are able to get these bikes to ride so well on the street yet
12:20 still give a very good level of road holding on the road.
12:25 The track and when you're riding in the canyons.
12:30 Now, we have this vehicle set up in dynamic mode, so the suspension is
12:36 altering the compression and the rebound damping in real time. But I have set it
12:44 up so the brake support, the fork support, the shock, all of these settings are
12:51 maxed out. So it's on the most aggressive, slowest setting that it can have in
12:59 dynamic mode. Now, I like to have it on the maximum setting because when it's in
13:08 a lower setting, the bike is just a little bit too soft and fast for me. I
13:13 like bikes that have good support, nice slow action in terms of compression and
13:19 especially rebound. And when I put it in that maximum setting, I wouldn't say that
13:25 the bike is still totally calm, but it is definitely more toward suspension
13:33 calibration spectrum that I value when I'm riding these motorcycles. Of
13:38 course, this bike also offers fixed damping, so you can set up fixed damping
13:45 settings if you like to. But honestly, this semi-active setup, once I put it in
13:51 the most aggressive setting, it works really well for me. Now, these Street
13:57 Fighter V4s are awesome because they have Ducati's tour de force in the
14:02 electronics department. There's an extreme level of adjustability in these
14:07 motorcycles. I'm running the highest power setting with the most aggressive
14:13 throttle response. Ducati's done a really good job evolving their throttle
14:17 response. The throttle response on these Panigale V4s and Street Fighter V4s,
14:21 and even the Multistrada V4 now, is downright excellent. Now, with this
14:28 $5,500 Acroponic titanium exhaust, a custom fuel ignition ECU map that
14:38 includes parameters specifically for DWC, DTC, all of those, that mapping applies
14:45 with this exhaust. And the mapping on this engine is just excellent!
14:53 Now, Panigales that roll off the showroom floor, anything out of the
14:58 Borgo Panigale factory in Italy, always kind of has rough fuel mapping. But the
15:04 mapping on this Street Fighter V4s is downright excellent. Very responsive
15:11 engine tuning and throttle response on this bike.
15:17 Yeah! Love this thing! God, this thing is so fun to accelerate on. Now, if Lucifer was
15:28 alive, this is the motorcycle he would ride. It is just so extreme, so wild, so
15:36 fast, so powerful, so charismatic. There are a lot of great naked bikes out there,
15:44 but none of them ride like this thing.
15:48 We rode this motorcycle after dark, and I really like the LED headlights on this
15:56 bike. They throw out a good spread of light,
16:01 it really allows you to ride this bike hard at night. But I do have a gripe. This
16:05 bike needs cornering head beams. For $25,000, it should have cornering head
16:12 beams, especially considering insane handling performance of this bike. Ducati,
16:20 for the love of God, add cornering headlights. Now, keeping tabs on
16:25 everything is this 5-inch color TFT screen. This screen, the size is decent,
16:32 but it could be a little bit larger. There are competitors out there that
16:37 offer larger, crisper, more functional dash displays. Now, I like that this thing
16:44 is loaded with settings information, but the switch gear, the tactile
16:50 function of the switch gear could be improved. When you're wearing gloves, it's
16:53 hard to know if you depressed something, and just the menu system and the amount
16:59 of doodads and displays is a little bit clunky. Ducati could definitely spend
17:05 some time improving the user interface. Now, to be fair, they have made great
17:10 strides, and this UI is better than previous
17:16 editions, but still, they could do some improvement in the UI. Now, right now, we
17:24 have black fonts over white background, but at night, this screen will
17:29 automatically turn over and be like our iPhone, where it's dark background with
17:36 white numbers, which I really like. Riding around in top gear at 672 miles
17:43 per hour, we're pulling right around 5,500 RPMs, which is crazy. We still have
17:48 another 9,000 RPMs left to go before this thing hits redline. Just crazy
17:54 power band on this motorcycle, but in top gear, engine doesn't vibrate
18:01 excessively. Engine has a real pleasing demeanor. It doesn't vibrate
18:06 excessively. The view from the rear view mirrors is pretty good.
18:12 Excuse me. Now, engine heat. We haven't ridden this motorcycle in dense traffic
18:21 or in stop-and-go traffic, but based on my experience with the Panigale before,
18:28 this engine throws off some serious heat. This isn't a motorcycle you're gonna be
18:35 riding on a hot summer day through LA traffic.
18:41 To be fair, Ducati has added cylinder deactivation. When the
18:50 engine coolant is over 160 Fahrenheit, the rear two cylinders deactivate when
18:57 the motorcycle stopped. That helps eliminate some engine heat at a stop. It
19:05 also decreases engine noise, so allows you to ride a little bit more
19:12 inconspicuously. Yes! Yes! I love this thing.
19:19 Now, California has a noise law. Vehicles are not allowed to emit over 95
19:28 decibels of sound. This Streetfighter V4S with the $5,500
19:36 Akrapovic titanium exhaust definitely exceeds 95 decibels, but I'm not
19:42 telling anyone. I love the sound of this motorcycle.
19:51 Brakes. This Streetfighter V4S rolls on radial mount Brembo's with a radial mount
20:00 Brembo master cylinder. It also has these cool accessory levers. These levers are
20:09 foldable. They have nice big adjustment. I love these levers. They have a
20:14 ton of adjustability. They feel really nice.
20:18 The brakes on this motorcycle are downright... they're unbelievable. They are
20:23 so good, especially when you max out the brake support setting with the Olean
20:31 semi-active suspension. It really allows you to use these brakes aggressively.
20:37 Now, not only is the actual braking hardware of this bike awesome, but I got
20:43 to hand it to Ducati and their ABS programming. Ducati has really led the
20:49 charge in advanced and aggressive ABS programming.
20:54 Now, even in its most restrictive setting, ABS 3, you have to be a very, very
21:03 experienced rider to even have an ABS intervene at a level where that's
21:09 actually going to hold you back. The ABS programming on this motorcycle is
21:15 quasi-race ABS programming. If you're a B or a C level racer, the ABS programming
21:22 on this bike will be good enough for you to compete on. It's that good. Other major
21:28 motorcycle manufacturers, even sport bike manufacturers, even superbike
21:32 manufacturers, don't have as good of ABS programming out of the box as Ducati.
21:39 Good job, Ducati. Don't think we're not paying attention.
21:44 Other electronic goodies, we've got DTC, Ducati Traction Control, Ducati
21:49 Heely Control, Engine Brake Control. We have it in Engine Brake Control mode 1,
21:57 which is the most amount of engine braking. I like the most amount of engine
22:02 braking when I ride these bikes on the street. Now, this dry clutch, this $3,500
22:10 dry clutch conversion also allows you to fit different diaphragm springs. You can
22:16 even have more or less engine braking. This is mechanical engine braking, not
22:20 the electronic engine braking that EVC controls by adding fuel to the engine
22:28 during deceleration.
22:32 Now, the electronics on this motorcycle, what I like about it the most is
22:38 just how much versatility you have. If you're a very high-level rider, you can
22:44 really pull back the electronics and that allows this motorcycle to be ridden
22:48 unencumbered. Conversely, if you're someone who's new to riding, even though
22:53 you really shouldn't be new to riding, if you're riding the Streetfighter V4 S,
22:56 just because it's such a high-performance naked bike, you can
23:00 still dial back the power, dial on the traction control, and put in a
23:07 setting that can allow you to ride this motorcycle relatively safely. And that's
23:12 what I like about this bike so much.
23:19 Now, we've got to hand it to Ducati. They've made great strides in the fit and
23:27 finish department. The fit and finish of this motorcycle is definitely improving.
23:34 I love the machining on the frame headstock, the handlebar, these fasteners
23:39 Ducati uses, the switchgear, everything is improving and Ducati is definitely
23:45 making great strides in the fit and finish. Now, for many years,
23:52 we're very far behind a lot of the big Japanese OEs, but it's good to see Ducati
24:00 closing that gap and making higher quality vehicles for us to ride.
24:09 Now, this Streetfighter V4 S has Ducati's accessory heated grips right here. You
24:17 push this button and the heated grips are on. It's around $350 for that feature,
24:24 and I like these heated grips because they get hot. In the hottest, highest
24:29 setting, these heated grips really pump out some heat. A lot of other motorcycle
24:35 manufacturers, they do heated grips, but the heated grips don't pump out the heat
24:40 like the set on this Streetfighter V4 S. It really makes riding in cooler weather
24:48 that much more comfortable.
24:52 Love the brakes, love the power, love the everything on this bike. This bike just
25:00 kicks butt.
25:03 [Music]
25:06 Yes, yes! I love running this thing through the
25:18 gearbox.
25:21 Now, this thing's obviously surprisingly civilized
25:28 here in the city, but God, when you ride this thing on your favorite back road,
25:34 this bike is just exhilarating to ride. It is absolutely exhilarating to ride.
25:42 This Streetfighter V4 makes me remember why I liked old-school Ducati
25:50 superbikes so much, because they just were so insanely fun to ride. They had good
25:58 power, good character, a charisma that other vehicles just don't have, and this
26:07 Streetfighter V4 S brings us back to Ducati's core roots, and then some.
26:16 Not only does it have Ducati's core fundamentals and roots, but it's got just
26:21 an insane amount of performance, an insane amount of of electronic
26:27 adjustability, and I just really like this bike. Fuel mileage we forgot to
26:34 touch on the MPGs. Now, if you can just plug this engine and not really get on
26:42 the pipe, this thing will get pretty decent fuel mileage right around the
26:48 high 30s, but realistically when you're riding this bike like it's meant to be
26:53 ridden in the canyons, you're gonna get fuel mileage in the high 20s,
26:58 low 30s. So if you can just short shift it, lug the engine, not rev her out, you're
27:04 gonna get high 30s. For everyone else, you're gonna get high 20s to low 30s, but
27:11 still, it's nice that you have the choice, aka your right wrist. Well folks, there it
27:19 is. Ducati's totally awesome 2021 Street Fighter V4S project bike deck to the
27:27 moon with Ducati performance accessories. Now, in the bike world, this thing is a
27:36 big deal. We get to ride a lot of cool bikes all the time, but this thing really
27:42 leaves its mark on me. I like riding this thing a lot. Let's do some Q&A real
27:50 quick for the fans. All right, let's do some Q&A real quick. Straight to the top
27:59 here. How is there over $20,000 invested in this other than the exhaust and clutch
28:05 bike looks stocked? That's a great point. Well, we've got the $5,000 magnesium
28:11 forged wheels. We have the $1,500 carbon fiber wings that generate 60-some pounds
28:20 of downforce at 160-some miles per hour. We have the awesome levers, the carbon
28:29 fiber everywhere, the seat, those awesome rear sets. There is a lot of stuff on
28:36 this motorcycle. Some of it's kind of silly, like the carbon fiber on the
28:43 instrument panel. Some of it's kind of not, like those awesome precision machined
28:49 rear sets, but the great thing about Ducati performance accessories is you
28:56 pick your poison. You pick whatever you want in the catalog. You put it on, you
28:59 don't put it on. Everything has Ducati's manufacturer warranty behind it. Other
29:07 than looks, how does this machine compare with the KTM 1290 Duke R or R when it
29:14 comes to riding on the street? Well, I haven't ridden the RR 1290, but I've
29:19 ridden the current modern 1290, and that bike's really nice, but this bike, no bike
29:25 accelerates like this bike. There is no other naked bike made in any displacement
29:31 category that accelerates like this vehicle you're looking at it, and that's
29:36 all you need to know. Are super nakeds a paradox because to actually use them that
29:42 that much HP you need a fairing? Well, kind of. That's what I always thought, but
29:48 now that I'm old and my body doesn't bend like it does on a sport bike, these
29:53 motorcycles are really awesome because they're just more comfortable. They're
29:57 more comfortable, and you can still wail, and maybe not wailing quite to sport
30:02 bike level, but 94% there, and you're comfortable, and that's why these naked
30:09 bikes are cool. They also look awesome. I mean, just like imagine pulling up at the
30:15 spot on this motorcycle like this thing is a looker. Alright folks, one more
30:21 question, Monster 1200S or Street Fighter? That is a no-brainer. This bike, I'm not
30:28 a big Monster 1200 guy, but a Street Fighter guy, V4 Street Fighter guy, I
30:33 definitely am. Alright folks, that wraps up today's MC Commute review on the 2021
30:39 Street Fighter V4S project bike. What I spend my $47,000, almost $48,000
30:46 as tested money on this bike, I wouldn't spend that, but I definitely would buy a
30:53 Street Fighter V4. I'd probably even get a V4S. I'm really feeling this
30:59 Ohlins semi-active suspension, and you know what? I would absolutely spring $3,500
31:05 for that dry clutch. You know what? I absolutely would spend $1,300 on those
31:12 rear sets. Now that Akrapovic pipe is totally awesome, but $5,500 is a little
31:20 bit steep for it, and it's just so loud. I feel like if I owned this motorcycle, I
31:26 would get arrested, or I'd be running from cops on a weekly basis, one of the
31:30 two. So I probably wouldn't do that, but I definitely would pony up money for the
31:35 dry clutch and those rear sets, and the heated grips, and the seat. There's a lot
31:41 of things on this bike that I would plop down my cash for because these
31:46 components just work really well. Alright folks, make sure to log on to
