Here is a shot of my 2006 that I bought off a member of this website. I have it for sale but I think that I'm fixing to just hang on to it. Just sold my YZ450 so I have some cash to fix up the RM really nice.

i've had rm 250s every year for since 2000!!! great bikes

- best year is 2006 so if you can find a real low hours 2006 then get it! the 06 has slightly more bottom end power than the later models (i think the carb intake boot is a different angle and slightly different porting to the later models) any of them 04 onwards you cant go wrong with though. currently have a couple of 2010 (k8) ones in the garage. Selling one of them for a new 450 though!

they come jetted very rich on the main as stock (as most bikes do nowadays) - as far as pipes etc stock is very good and probably the best set up for most people. I run mine with either the stock or fmf fatty front pipe and pro circuit r 304 silence, v-force reed block. Boyeson rad valves work really well too. Instead of the stock gearing (13-50) we go to 13-51.

alot of slower riders actually want to tame the power down from stock and go with reed spacers/ flywheel weights, i found that these tend to deaden the power too much (make it feel flat) and preferred the stock set up with minor mods like light porting work/ pipes etc.

- 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.

They really are great bikes, handle like nothing else! we tend to set ours with the sag set so the back end is real low- i feel that this helps in the corners.

Anyone using a FWW in the sand on their RM? I have a BPM built engine with pro circuit pipe and silencer with vforce reeds. I have a heavier FWW I think it was 12.5 when I weighed it. I tried it once when I was up north and it did give the bike more traction but I thought it slowed it down some which was fine for a hardpack track but under loamy or sandy conditions Id like all the power I can get.

Maybe try a 6oz.
Did you read the previous pages lol? Not being an ass but lots of good info about your ? in this thread. Dowd owned sand and he ran heavier fww. I'm kinda with you i have a 6 oz but havn't been able to really test it.

Hi Guys


I am looking at buying a Hinson billet clutch basket for my RM250..

Question: Does anyone know if you can fit a standard pressure plate and internals on the Hinson basket?

Cheers 2 stroke brothers
May you Braaaap with crispness eternally and not let the lazy, expensive, heavy 4stroke man hold you down.

have you priced a new cylinder from an RM 250? its $775. good thing you can replate...but I have seen many busted up cylinders that cant be replated. and if it was my bike, I wouldn't run a heavy flywheel weight. Those RMs had a really trick asymmetrically balanced crank from the factory. It helped the RM hook up. but with any mod or part in question, the only good way to know is to try it for yourself. if you don't like it, sell it on e bay or something

Speaking of flywheel weights. I just did the motor on my 13 KTM250SX (lowering the & cleaning up the cylinder & doing the head & powervalve & boring the carb) & the guy who did most of the work was at my house this morning getting some thinner base gaskets so he could lower the cylinder on a friends of ours new 13 250SX too & I was telling him about this topic & he said to take a look at the size of the flywheel weight that comes stock on my bike. He said it appears to easily be around 20-25oz.

Your '13 comes stock with a flywheel weight of about 20-25 oz .....now that's cool. A manufacturer that is catching on, I like that.

Hey fellas i'm really interested in the RM250, I want to go back to the two stroke. In your opinions and experience what year(s) do you feel were the best for the RM250 and why? Any input from you guys would be such a help, thanks.

That's a bummer you're getting rid of it. 'm kind of in the same boat , and am thinking of selling mine , but it's mainly for extra room in my shop. I hope to get a 2016 YZ 250 2 stroke this spring / summer sometime and it'll be cramped in my garage if I keep the RM. BUT....I'm holding onto her for now , as I may regret selling it. Won't hurt to have two bikes , just wish I had more space.

Side note : I went back to the 2 strokes because the 450's seemed to of made me lazy , and I wanted something a little more challenging to ride. It seemed I spent more energy trying to hold onto the 450 , where as the 2 stroke I can kind of muscle it around for longer periods of time without getting as tired. Besides that.....it was nice getting back to something I obviously missed. This past summer on my RM , I had some of the most fun riding , I can't see myself ever getting another 450.

Same reason I got the 2 stroke, and for cheap rebuilds then I started hitting some tracks out in CA and realized the torque is needed, the way people ride in lines makes it tough on the 2 stroke also but I agree the sound, smell and fun is on the 250, got a new RM 450 and love it. Need to make some room also for the old guy 500 Husky dual sport I may try and pick up but they are a bit pricey!
