Motorcycle enthusiast Frank Desborough ran a small engineering business, based in Commercial Road, Wolverhampton. In 1951 he built a racing machine to compete in the first 125c.c. Isle of Man T.T.

He designed a special engine for the machine; a 125c.c. water-cooled, horizontally opposed, twin-cylinder, 2-stroke. Unfortunately it was not ready in time for the race, so he built an engine using Villiers and B.S.A. Bantam parts.

The motorcycle was possibly the first machine in the world to be fitted with disc brakes. Unfortunately it was not a great success, nothing more was heard of it, and no others were made.
