I put a bit into my 250, but it was all cosmetic for the most part. HIDs, LED bulbs in the turn signals, fender eliminator, shimmed the needles (which made a night and day difference in cold starts) and pulled the snorkel from the airbox. That and I put on some BT-016 tires when it was time to ditch the stock IRCs. Oh, and heated grips. Forgot about those.
