2009 YAMAHA YZ250F, IN STOCK!!! WE DO NOT COLLECT SALES TAX!...WE DO NOT COLLECT SALES TAX!...STAYING ONE STEP AHEAD IS WHAT WE DO For 2009, we bump the AMA Supercross Lites Champion YZ250F's aggression level even higher, with changes to the exhaust and ignition systems that sharpen power delivery and response off the bottom and midrange. Then we made sure you could put it to the ground more precisely than ever, with subtle but significant chassis upgrades to what was already the best-handling, best-suspended bike in the 250 class.
