This is a clean RACE BIKE. I have thousands invested in performance work and suspension work. If a modification is available this bike has it!! All together I have over $11,000 invested. The motor has a set of stage 1 Hot cams in it (stayed with stage one to keep durability. Head is ported and polished, Carb mod to do away with bottom end bog. It has a FMF power bomb header. The radiator has been enlarged and has weld on bracing (from ICW). Suspension is valved and set up for a 160 lb. rider in street clothes. This 250f has the bottom end that yamaha lacks from the factory. Basically all the money I invested was to keep me from whining about the power lacking stock motor. Without a doubt this race bike has been the best I have thrown my leg over! The only reason I am selling it is because I am riding 450's next year and want to purchase a back up 450. Motor has all new valve train parts, High compression piston, and all clutch components (only one ride). This bike will easily withstand any punishment you throw at it! Bike has hour meter installed the day it was brand new! Call me for pics or to set up a time to see it! -Jay: 740-974-7674. fight_413@hotmail.com
