I traded my 14 rmz450 to a great condition 07 rm250 and literally cannot find any info online about this bike. Anyone have any articles, etc they'll post?

To start off those are 2008 graphics. So maybe you bought an 08?
The clutch sucks. Very grabby. Put a better basket in it if you want to get decent starts or like to ride slow technical stuff. Great bikes. Tighten the steering stem and play with sag because these bikes can be nervous if you don't set them up. That's really all these bikes need.

What are you trying to find? I do a lot of computer researching on bikes just for fun I could probably tell you a few things.

Actually RCs input caused those changes starting in 2005, I talked to DeCoster about that in great detail at Rio and he explained to me exactly how it was done with the Engineers from Japan.

This is what Dirt Bike had to say about these bikes:


Best of luck with your 2007.

The 06-08 models were basically the same with BNG's. Owned an 06 & it was a decent bike, but could never get it to handle good even after having RG3 do some suspension work. The rear felt sketchy to me at higher speeds with a nervous feel to it. It turned good & the engine had a decent mid-top power with not much down low with a PC pipe installed. If the rear felt more stable it would have been a solid all around bike for me.

Maybe it's just me but I always ran the shock spring rates a little soft and they worked perfect.

It might be an 08. I haven't picked it up yet, so I have only ridden it once and have it the once over.

Showa 47mm.

Newer model RMZ shocks are a direct fit. I know RMZ forks can be made to fit but not exactly sure what is needed.

Do a search on those bikes in this forum. There's a lot of info.

I had an '08. Really good allround bike. Struggled to get the fork as plush as i would've liked but it was a fun bike. Motor was great, i have a V force reed valve and well jetted & it ripped.

Yeah I wasn't able to get a good setting on the balance of the chassis with different settings so I was never confident on the RM. The right set up seemed very temperamental in my experience.

Good bikes I had a 08. Handled well, and pulled well once I opened the power valve up. Put some v force reeds in it. Gear box went on mine, notorious for been weak. Sure you'll love it though

.... just ride it like you stole it !!!

They don't need much, You don't need to go crazy.
- go oem top end and clutch packs only
- w/c perch did wonders w/ the grabby engagement
-- YEs type F atf works the best for me. Change every other ride or after a sand track
- jd jet kit (easier for me)
- Sunoco 110 @ 32-1 w / 927

For comfort and feel I liked the fat bars like I had on rmz, so I picked up the same bend. Plus it helped when I jumped back and forth between the two bikes
Added a heavier fww to clean up the chop in the team and smooths the hit slightly or just more linear
Showa great on both ends w/ a revalve

*** Only issue is I need to start riding... too much work this summer

The RM suspension is better IMO. I own an 06 125 and RM 250 plus I have a 13 and 16 RMZ 250.
48mm forks on the 2013+ RMZ's.

AFAIK. The 2010 to 2012 RMZ 250 forks are a direct fit with the 06+ RM's. But different axle sizes.
Top triple clamp from the 06+ RM 125 and RM 250, are the same as the 2008 to 2016 RMZ 450 and the 2010 to 2015 RMZ 250.
Bottom clamp on the 2013+ RMZ's is to large in diameter.

A ,lot of people use the YZ 250 pistons in the RM 250's.

Keep the rear suspension linkage and head stem bearings well greased

You should be able to find a new Hinson clutch basket, good luck finding the other parts for an 06+ though. Only chance is 2nd hand.

BUD racing do a bottom tripple clamp that uses the newer RMZ front guards. You should be able to get one from Applied Racing also.

The seat foam sucks. The Factory FX foams are made by Gut's Racing, Or you could get a complete seat from SDG.

IMO, the Boyesen Reed valve is better than the V-Force.

2nd gear is the one that normally shits itself. I had my gears etc Isotropic Super Finished.

Here's a copy and paste for a transmission mod that another member posted a while back. I went to do this mod but there was no movement, "floating", in my gears, everything was tight and it shifts like a hot knife through butter. I've had no dramas with m y 250 transmision, I did have to replace 2nd in my 144cc though. I just replaced them all and and had them ISF'd.


- 3rd and 4th drive gear and 5th driven tend to wear out on the dogs about every 60 hours running time (on average)Theres a shim washer and circlip on the back of 3rd drive gear thats a little too thin and allows 3rd to 'float' a little too much. We add a thicker shim washer there, and also a more heavy duty circlip- the stock circlip can concave (or pop off all together) if you stomp on the gear lever too hard, allowing the gear to move where it shouldnt. This will make your gearbox last alot longer!
Also, when you check your clutch you might want to check the gear selector pin as we have had these work loose after a few hours- we normally remove them and loctite them when we get the bikes, same with the screws on the selector barrel.

Yep lol. Sold it to the guy I bought the rm from. I loved the rmz, but it was a little too much for my lazy riding. I'm happy now lol. I've always wanted an 08 rm which I found out this is . I picked it up at midnite just now
