Yellow. This is the S model with lighter wheels, better suspension, etc. 21,XXX miles, dealer valve service at 18,000. Looks great, runs great. Stock exhausts plus Termignoni CF exhausts and chip included (CF is cracked - take off from another bike). This bike has not been messed with and the only thing "wrong" is the low fuel light stays on. Looking to sell for $4300, or trade for '04 or newer 600CC track bike (must have a slipper clutch). I'm near Novi, Michigan. PM and I'll email you back.
