I have a 2001 X-1 Lightning, with 1030 actual miles on it. D&D performance muffler, Force-winder/side air filter and H-D ECM race kit(#91437-99Y) on the bike now. Dino'd at 110 H-P. Have ALL stock parts, too. I am 65 and have some balance problems and the bike is too much for me--I have a BRP Spyder that keeps me happy & a H-D Ultra(hardly used). I am looking for a new home for the bike. Write for more info at [email protected]
