1968 CZ380 Tilkens Monoshock

The first monoshock bike ever built for motocross. This is the actual bike built by Mr. Lucien Tilkens who sold the patent to Yamaha. It is in all original unrestored condition. The bike was originally Sylvian Geboers 1968 works CZ380. In 1971 it was converted to a monoshock design by Mr. Tilkens at his shop in Belgium using a gas Citroen car shock. The idea was that transferring the rear suspension load to the steering head vs the rear frame rails was a better idea. The long travel that was the ultimate result and benefit was purely an accident. It was tested by Roger DeCoster and Sylvain Geboers for Suzuki and they found that they could go much faster on the Tilkens CZ than they could on their works Suzuki's. Suzuki declined to buy and Torsten Hallman and Yamaha came into the picture and the rest is history.  The bike was also raced by Guy Tilkens (Mr. Tilkens son).  This is the original bike that started long travel suspension. The suspension on the bikes you ride today, trace back to this very bike. A real piece of history. This bike will be put in a glass case in our museum.  Look for a full feature on this bike in the near future.
