I have a 2003 Kaw zx636. The bike has 4000 miles. Stock motor has a power commander and full akrapovic exhaust system. Galfer oversize rotors and braided brake lines. Hotbodies body kit. Dunlop Q3's with one ride at NCM advanced class. I have owned this bike for 1000 miles. I have run renegade ec98 fuel since i have owned it I also changed oil after every ride. (i know thats overkill but im a maintenance nazi) This bike runs like a clock and would be a great starter bike for anyone getting into the sport. I has one low side from previous owner and to my knowledge that is the only time the bike has been down. Please call or text 270-498-4696. I can send more pictures upon request. I am located in Bowling Green, Ky so of course i can bring it to NCM if you want to try it out.
