I have for sale a C&J XR/XL 500 chassis, made for 1979-1982 XR/XL engines. Built for all different disciplines of off-road racing. Frame was a prototype built off of the winning single shock C&J flat track bike. I purchased this with the intent of building it and racing vintage motocross but plans change. Included in this deal will be the frame itself, swingarm, shock, foot-pegs and a box of parts. This chassis is a piece of vintage Mx racing history, I have confirmed with the owner of C&J that this frame is legit and only 3 were made to this spec. $3,000. Thank you for your time! I am located in Southern California
