I made one about 4/5 years ago. Superb you can have all 4 wheels moving in all directions , locked for steering when moving along longer distances and braked. I have had the MuZ on it for a major service, am GR650 Suzuki and just been able to handle the Silverwing scoot with its xtra long wheelbase, and the TS185 There were some pics in the gallery back then.
