This bike was mainly used to trail ride with my son the first few years. I would go maybe once or twice a month. Then, when he got older, we would hit the track a bit. It has never been ridden in the sand dunes. It has been through one top end change where the cylinder was sent to Pro Circuit to be honed out to run with race gas. VP Fuels C12. Suspension done by Too Tech Suspension. It has only been ridden 2-3 times since the new top end. The tires are in good condition. No problems with the bike whatsoever.  Very strong compression with ne piston and rings. Excel Rims Please contact me if you are interested.
