Its becoming more and more difficult to find RM parts these days. Ive read a few threads saying that some of the parts from RMZs will fit on the last gen RM (04-08). Does anyone know if the axle blocks from the RMZ will fit the RM? What other parts will interchange?

Axel blocks will not fit. Rmz uses a bigger axel. Can't get oem axel blocks? Zeta makes aftermarket axel blocks

I actually have a set of red Tusk axel blocks, I am just wanting a set of the Bolt axle blocks that have the adjuster bolt made into the block. No specific reason other than I like the looks of it.

RMZ axel blocks would work if you made a sleeve to compensate for the different axel size (RM is smaller)
Cooper 688 did this to his RM (see his insane RM250 bike check)

Quite a few RMZ parts work on an RM, some take more work than others.
I have a 2008 RMZ Ohlins TTX shock on my 08 RM250 (direct bolt on fit), most RMZ shocks will work on an RM.
RMZ forks will work if you use an RMZ front wheel and spacers, newer RMZ front ends have larger diameter forks so you will need to bore out your lower RM clamp to suit (another mod I've done to mine and put an entire seasons riding on)
Some RMZ triple clamps bolt strait on (such as Pro Circuit) Others can be made to work if you use the RM steering stem (Neken). Steering stops would need to be added for both however.
An RMZ front brake system is a direct fit, along with RMZ 270mm oversize kits (and Ride Eng Brake Caliper - dbrunski can confirm this)
I've used an 05-07 RMZ linkage arm (1.5mm longer Pro Circuit Link) on my RM, this was a direct fit. I've not tried a linkage from a later model RMZ though.
RMZ clutch fibers work in an RM
RMZ Reservoir Caps fit RM's
Oil Filler Caps are the same

The following WILL NOT fit from RMZ to RM:
Seat
Rear brake caliper/bracket
Clutch Basket
Clutch Hub
Pressure Plate
Swingarm
Rear Wheel (it might with different bearings and custom spacers)
Brake Discs
Headstock Bearing Kit


If your curious about other parts I have missed out then shoot me a message. I have a 15 RMZ450 and 08 RM250 so I can have a play and see what works and what doesn't

I've fitted a Motostuff 280mm blade brake kit to my 08 RM125. RMZ discs are not the same on later models, Matching part numbers on partzilla says that 06 RMZ250 shares the same front wheel assembly as the RM125 wich does open up a few aftermarket parts. I dont think that Motostuff listed any suzuki stuff older than 08 or 09 when they went to updated front end. So I used a YZF front disc on the RM hub, its exactly the same. I also used a brake calliper bracket from an 97-02 CR250 after being told it would fit perfect. It does work but positions the caliber a few MM too far out on the outer edge of the disc. But after feeling like a total dickhead dbrunski125 enlightened me to the fact that RM & RMZ calliper brackets are the same from 06 to 2017.

Russ, you are a man after my own heart. I'm doing the same gig, rockin' the new RMZ and keepin' the old RM 2 strokers alive!

Bump to an old thread! Any clues about shift levers? Will RMZ parts fit RM's and vice-versa?

Russ I know this is an older comment but great info man! Do you know if most of this applies to an 02 RM125 too?

The shifter won't interchange.
Nor will the wheels.

Hmm the 02 125 is different in a lot of ways to the 08 RM250.

Pretty much all of what I listed above wont actually work with the 02 125, as a lot of things such as suspension and linkage, frame etc are a lot different on the 02 125. Therefore the rear shock wont interchange. Clamps from an RMZ may fit but the offset is way different between RMZ and 02 RM125. I'm pretty sure the brakes are completely different too, but may still interchange. 125 clutch parts are different so none of the RMZ clutch parts will work in the 125

Somewhat related, what keeps and 04-08 RM250 pipe from working on an 03? How difficult would it be to make that newer pipe fit the old bike?

Super old thread but can anyone measure the linkage for the newer bikes? I am trying to lower a 96 RM125, and its before they went to the straight rods for the pull link, its a fully cast & welded piece. Wondering if the newer stuff would fit.

One of the mounts is different. I think it’s the lower pipe mount by the water pump but I can’t remember for sure.
The engine from 03 to newer were very similar. The 03 engine has a lower exhaust port and slightly smaller sub exaust ports, different inner clutch hub splines also changed for every year rm, lighter power valve governer spring, lighter shift detention spring, different carb jetting and richer carb slide, slightly lighter crank and of course slightly different pipe mount.

Rear wheel will not fit... ever, the spacing between the sprocket and disc is a lot different.

On the front, it can be made to fit, but you will have to mess around with axle, bearings and spacers

Old thread new comment but good info in here

I’ve been building my 07 and have been testing with a lot of different bike parts so I can have aftermarket oarts

As for wheels on my 07 RM250

The front wheel I used an 03-08 tusk (ordered for 2008) yz250 as the share the same axle diameters and used my stock wheel spacers.

The rear wheel is a different story and this is where people with bad info should never comment comes into play so I seen multiple posts saying the 06 KX250F rear wheel works, so I ordered one, it does fit perfectly in the swingarm I’ll give them that part but the axles are different, after looking for a place to make me custom bearings to fit the hub I had 0 luck, then I thought about boring swing arm and everything to use the kxf axle..I ended up finding bearing sleeves on amazon that were (22mm ID and 25mm OD 20mm long) 3 of them fit perfectly into the hubwith with enough sticking out tonsit the wheel spacers on greased the bearings (not much grease from factory inside the bearing after pulling dust covers off) and that’s how I got the KX250F wheel to work on my RM250
After a little research i found that the 03-08 yz250 also shares the same axle diameter and only obvious thing I could see is the 2 bearing hub compared to 3 in the Kawi and Suzuki’s, I have not tested a yz250 rear wheel but I will eventually just to see

Also used a 15 RMZ hammerhead break pedal with RM clevis and RMZ return spring

Can you clarify if it was a 250 or 450 brake pedal? Direct fit or did you have to do any work to make it fit other than the rm clevis?

07-18 RMZ250 hammerhead brake pedal it it fit on perfect and the only other thing I did was change the rm return spring to an RMZ spring! Also on the YZ250 front wheel the wheel spacers need to be shaved down to make the rotor line up with the caliper I don’t have an exact amount yet but will update as soon as I do

This is the one I ordered I went back into my purchase history to look

With a little bit of welding you can put an rmz 250 subframe from I think 2010+ not that it really matters now that polisport is making a restyle kit. Linkages from like 07+ rmz's fit I believe. Mines from a 2010 I think but they are all almost the same and will work. Photo

I actually screenshotted your bike and was showing my buddy cause I wanted to do it, also read your write up about it! Really cool and good info you put out the only doubts I had was my silencer because I’m running a bills carbon silencer are you able to cut and re weld the exhaust bracket to fit?

You might be able to or you could just make a mount off the subframe to fit the RM exhaust and then you could switch in the future if you ever wanted to

That’s what I was meaning, also the reed spacer is another question is that a spacer block with the stock reed cage you have? I have a small reed spacer with VForce reeds if you could measure about how far it sticks out from the reeds to the case for me that would be greatly appreciated!

Old thread but I am back, so I finished up my 07 build a while back in order to run that hammerhead brake pedal from the RMZ you have to cut the return spring mount off the pedal and use the FASST CO. Master cylinder return spring kit (20$) and that’s it works perfectly and can get way better pedal adjust ment with that kit

Hey Guys! Does anyone know if a 2018+ RMZ450 Rear Master Cylinder will Fit on a ~2006 RM250? I'd love to get the new master cylinder as it is significantly cheaper than a new replacement for the RM's and is a lot better looking.

I updated my front master cylinder with one from a 2013 CRF450R and I love the feeling. My old rear is clapped out and I want to upgrade while saving money if possible

Thanks!

Please let me know.
