1 1/4 Axle. CKS blueprinted. Blue housing. Was originally for 100cc Controlled. Only two races. Then used 2 seasons with PP Can (Yamaha). Sat on shelf last 10 -15 years. Very good condition
I acquired it from a friend who got out. I ran SMC myself so it has been on the shelf all these years. All original with quick adjuster kit. I can txt pics. Can’t email digital at the moment.
