- 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.

Picked it up with low hours on it and the trans lasted a few seasons until just recently. Rebuilt it twice this year and still funky.
Ergos aren't the most comfortable for me. Suspension is just ok. Motors rip though. While they turn amazing they feel super twitchy to me. Never been able to get 100 percent comfortable. Going to try a cr250 next
My RM dropped into neutral off a downhill triple and I endoed it out pretty bad. Concussed myself and fucked my head up for a few months. Didn't think a concussion would suck that much and don't want to do it again!
I rode an 05 CR250 and didn't really like anything about it, but the 02-04 steel frame YZ250 is a great bike IMO. On PulpMX Reedy, Vuillemin, Ferry, and MC even said that era YZ frame was one of their favorites. The 06+ alum YZ250 suspension is really good too. I've ridden a few KX250s and they are OK too. The RM and YZ engines are way better though.
Back in 2015 I traded an '09 CRF 250 that my brother rode a lot from brand new to 2015 for a guy's '08 RM 250 and to top it all off he gave an extra 1000$ with the RM. Safe to say I got the better end of that deal lol.
Don't think I'll sell it. I'd like to do a build with it when I have funds available. I already know what I want to do with it but it's far from being a budget build and I don't have those kinds of funds at the moment. Not only that but if they don't come up with a solution to cure paralysis I'll never be able to ride it. In the mean time my brother can use it whenever he wants.
In 2006 I was debating between purchasing a new YZ 250 or the RM 250 since the dealer sold both brands. I decided to go with the YZ since all I had ridden before that were Yamaha's and never had problems with them. Great bike but I never got along with it and in '08 I decided to try a KTM so I settled on the 144sx. Sadly that's the last bike I got to ride.
Maybe one day I'll get to ride again. I sure hope so anyways.
It better not be all electric by then either lol.
1999,2001, and currently a 2005 paired with a 2001 RM500(KX 500 engine in it)
I have more fun on the 2 strokes than the RMZs but they are harder to ride.
Buying a new updated RM250 with spring forks is a pipe dream of mine. A smooth 350 would be better...
My 92 made to look like Larry Wards 90 and my 06. I think they're neat

So i'll update.....
The 2008 RM250 I originally posted in this thread is now sold.... but was replaced with a super low hour 2008 RM250. I converted it to Enduro as I fancied trying something new. It didn't last long as is now back in MX trim! but here's how it did look
My 1989 RM250 is still going strong and features loads of updates, I will snap a proper picture once its complete. But it now features forks from a 1994, handmade PPS pipe and I have a custom built Ohlins shock to go on it too! Cant wait to take it for a rip in the next month or 2
I need to see that '89!!!
What frame guards were on that black one?
You will like the KYB set up, its really good and looks even better in person.
Lightspeed carbon frame guards on the 08. I was lucky to score those as well as a lightspeed sump guard all in near new condition. Definitely the best quality carbon stuff I've ever used.
Picking up the new Ohlins shock and revalved forks for the 89 this weekend! Just waiting for swingarm bearings to arrive then I can get her built back up and photographed. I'll make a Build Thread for it eventually.
I chose to go this way after riding some yamaha's recently, had the triple clamps fabricated (RM stem pressed into KXF clamps) and I'll see how it works. There will be a slight (0,5mm) change in offset but I don't think it will be enough to notice.
How did you like the KYB rear shock (the one off newer RMZ's)? I have one on the way from US.
Looking forward to your build thread, sounds very promising!

Built this last year. Bike runs amazing, still has the original piston in it!
The KYB shock was okay, it was set up as my enduro shock and because my 'enduro career' came to an early end, I didn't really get the chance to properly test and set it up. But I'd say it has the makings of a good shock, lots of adjustability! Looks smart too.
Now how do I explain this to my wife? LOL "Hey babe, I know I already have 4 dirt bikes in the garage but guess what I just bought!" HAHAHA
2005 rm 250
