how to make an 02 250 RM more trail friendly?

hey stevet
number one mod would be a bigger fuel tank. On my 02 RM125, i'm lucky to get an hour, maybe a bit more, out of a full tank. Yours being a 250cc, you would get maybe 30-40 mins more.
If you really want to go places, and aftermarket oversize fuel tank would be a wise investment i think..
Other than that, get some quality case protection, hand-guards....

Have fun

You're going in the right direction with the flywheel weight and the larger sprocket. Don't forget about bark busters and engine guards. I've heard great things about the Reckluse clutches, but I haven't ridden one (yet).

If you are going to be riding rocky terrain, you might give some consideration to putting an 18” loop on your rear rim. I would also have the suspension revalved for your weight and use. With those changes you’ll have a bike that Rodney Smith would be glad to call his own :cool:
