Here is a 2006 R1. Its about 1500-2000 away from being a fully functional track bike. No title with this one. Owner is still paying off the bike. pick it up for 2,200
Will need forks, stay, cluster, exhaust, subframe, rear tire, upper triple bridge, rear set pegs, air box, tank and body kit. Got a set of track skins for it amd some expensive aftermarket parts like exhaust, rearsets, brembo master, etc.

Left side frame rail will need to be rewelded, or you can find a blank frame on ebay for 200-400 bucks.
