Racing bikes 1969. (eyesight not up to racing speeds so I retreated to building/tuning) End of 1970s m/c accident ended m/c career. 1990s worked with John Britten on engine concepts. I can design a motor, I can design a frame. I don't know the current and recent motorcycles. I don't have deep pockets. Have lathes and mills, CNC and conventional. Regards, Greg.P.

I could equally design completely new forks and machine them, but if existing forks could be shortened it would cut costs drastically.

In that case, don't buy it, look for something that does what you want without having to make major modifications. Personally, I was thinking about buying a 3-wheeled bicycle and adding a 49cc moped motor to it if I ever deteriorate to the point where I can no longer balance a 2-wheeler... |
