I have a 2006 600 mod for sale. It has only been raced a few times. It has twin pipes(crank shop), vforce 3, high comp. and low comp. heads. It comes with 5 and 10 gallon tank. It also comes with two tracks (136x2 and 121x1.75) short track drilled for studs but are not put in (box of studs also go with sled) Overall it is in great shape and is ready to race or ride in the mountains or everything is sold with to trail convert.
