00:00 What's up everyone, Andrew Oller with Dirt Rider here and today we're going to tell you
00:04 some important things you need to know about the 2024 Suzuki RMZ250.
00:14 This bike has been unchanged since 2019 so all this information will apply up to the
00:18 2024 model year, but Suzuki is offering something special this year.
00:22 For 2024, they're offering what they call the RM Army Edition promotion.
00:27 What that includes is a full Pro Circuit T6 exhaust system and RM Army Edition graphics
00:33 kit by Throttle Syndicate.
00:35 This promotion runs through the rest of the year, so if you buy a new 2024 RMZ250 before
00:40 December 31st of 2023, you get both these items completely free of charge.
00:45 You just have to fill out some paperwork at your local dealership.
00:48 And by the way, the retail price for this RMZ250 is $8,099.
00:53 So going into more detail about this Pro Circuit full exhaust system, we have this stainless
00:58 steel header pipe with a RC4 resonance chamber from Pro Circuit.
01:01 And then moving further back, the muffler is made of titanium, basically from there
01:06 all the way back to here.
01:07 And then we have a carbon fiber end cap.
01:09 Very cool.
01:10 The muffler also comes equipped with a spark arrestor.
01:14 It's United States Forest Service approved and easy to remove, just an Allen bolt right
01:18 here so you can pull it out for a little more bark and a little more power.
01:22 The heart of the RMZ250 is a liquid cooled 249cc four stroke engine with a dual overhead
01:28 cam cylinder head layout and center port exhaust.
01:31 It has a 77mm bore, 53.6mm stroke, and compression ratio of 13.75 to 1.
01:39 Transmission is a 5-speed, which is par for the course for most four stroke motocross
01:43 bikes.
01:44 Fuel and air are sent into the engine by a 44mm throttle body.
01:48 So here at Dirt Rider, we're really fortunate to have our own in-house dyno.
01:51 We've run this RMZ250 and it made 36.9 horsepower at 12,100 RPM and 18 pound feet of torque
01:58 at 8,700 RPM.
02:00 Even though those aren't class leading figures by any means, it still makes more than the
02:04 stock exhaust system.
02:05 So props to Pro Circuit on that.
02:07 Something else to know is we put the RMZ250 on our automotive scales with a full tank
02:11 of fuel and it came in at 237 pounds.
02:14 Most of you have probably noticed this already, but in case you haven't, the RMZ250 still
02:20 is a kickstarter.
02:21 It's the only 250F motocross bike in the class to have it and quite frankly, we're
02:25 really hoping for electric start soon.
02:27 As far as tuning power, Suzuki still uses couplers, which means it's only one of only
02:31 two bikes in the class to use such technology and not have a handlebar mounted engine map
02:35 select button.
02:36 Suzuki does offer more EFI tuning options with its MX Tuner 2.0 system, which comes
02:42 free with the bike, but there's a bit more hardware involved and it's a bit more difficult
02:46 to use than some of the other bikes.
02:47 Next, let's talk about suspension.
02:49 The RMZ250 comes with one of the best stock forks on the market.
02:54 That's KYB's AOS coil spring fork.
02:57 What you should also know is the fork spring rate is 5Nm.
03:01 That is incredibly stiff, especially for a 250 four stroke.
03:05 For reference too, that's the same setting that most 450 motocrossers come with.
03:10 And with that super firm setting, that means this right here, the compression damping adjuster,
03:15 is going to be your best friend.
03:16 For most riders under 200 pounds, we'd recommend going at least a few clicks counterclockwise,
03:21 softer.
03:22 And at the bottom of the fork lug here, we have the rebound adjuster.
03:26 So to help give you that softer feel, you can go out as in counterclockwise on that,
03:30 which will help the suspension get back to the top of the stroke and give you that plusher
03:34 feel you're looking for.
03:36 And adding to the Suzuki's awesome looking appearance are these gold upper fork tubes.
03:40 They look amazing.
03:41 Further back on the bike, we have a KYB shock, which has a spring rate of 52Nm.
03:47 Not quite as over sprung as the fork, but still pretty stiff nonetheless.
03:51 The good news is this shock is very adjustable.
03:54 We're talking a triple adjuster body, which includes low speed compression, high speed
03:59 compression, low speed rebound.
04:01 Then at the bottom on the clevis by the linkage, you have high speed rebound.
04:05 The RMZ250 is built around an aluminum twin spar frame.
04:08 And although some aluminum frames can have a bit more flex, this one is a bit more rigid.
04:13 So you feel a bit more of the track surface when you're riding, regardless of where your
04:16 suspension is set up.
04:17 But the good news is it helps it corner like you wouldn't believe.
04:20 As far as ergonomics go, Spikes very agreeable.
04:23 The rear shrouds aren't ridiculously wide, nor are they super skinny, but again, a nice
04:27 middle ground.
04:28 And then as far as the handlebar layout, it's Renthal's fat bar in the 821 bend.
04:33 Again, very easy to get used to.
04:35 I'm about 5'9" and I don't think I'd change the bar if this were my personal bike.
04:40 And we also don't have a whole lot of buttons or switches.
04:43 Obviously no electric start button here.
04:45 And then we have the kill switch on the far left here and Suzuki whole shot assist control
04:49 here a little bit further in on the bar for those who are racing.
04:53 Much like the Yamaha YZ250F and Honda CRF250R, Suzuki uses a cable actuated clutch for its
04:58 250.
04:59 Keep in mind though, that it's a bit firmer pull at the lever.
05:02 For the front brake setup, we have a Nissan dual piston caliper that grabs onto a 270mm
05:07 disc.
05:08 And for the rear brake setup, we have a Nissan single piston caliper that bites onto a 240mm
05:13 disc.
05:14 Contacting the ground and providing traction, we have Dunlop Geomax MX33 tires.
05:19 And a quick fun fact, Suzuki was the first manufacturer to use these tires on its production
05:24 motocross bike right here on the RMZ250 back in 2019.
05:28 So there you have it.
05:29 The important things you need to know about the 2024 Suzuki RMZ250.
05:34 Thank you all so much for tuning in.
