My 03 RM250 was stolen last week so it's time for a new bike. As much as I love 2 strokes I guess at 40 yrs old it's time for a 4 stroke. Being the only guy in a group of 20 riders that I ride with every weekend that has a Yellow bike on plan on staying Yellow. I have read all the reviews and have a few questions. 1) I thought I read that the triple clamps were adjustable for taller riders.... true ?? It would be nice not to have to buy a new top clamp. 2) I ride strickly MX am 225 without gear and am a b rider. Does the bike only need new springs or is a revalve really necassary ?? My 03 needed a revalve but the mags act like the new suspension is really great. 3) I like a lot of low end power, is going to a 50 tooth rear sprocket required ?? Or is the new Boyesen shot enough of an improvement ?? Anything else I should be aware of ?? My dealer has two 450's and I can get it for $5,999.00 plus all the taxes and BS.
