FACTORY YAMAHA TY
In this section, we will discuss the factory TY models, as well as other tuners who have attempted to improve the Yamaha TY's trial capabilities. To begin with, here is the very first TY model with Christian Rayer on the first pre-production Yamaha TY, which he developed with the Yamaha factory:

The great “Mick Andrews” was entrusted with the development of the motorcycle by Yamaha under his new contract, which began on March 1, 1973.
1973: The first historic successes
Historic victory for the first Japanese rider in a European race on April 1, 1973, riding the TY 250 (above).

This is the machine with which Haruo Kimura won the first Japanese trials championship in November 1973.
1974: The innovation of the cantilever
In 1974, the TY 250 OW10 with cantilever, the single shock absorber system developed by YAMAHA.

Back to dual shock absorbers
Back to dual shock absorbers with the 400, the cantilever setup is not entirely satisfactory.
1976: Improvement of suspensions
Still classic shock absorbers with the TY factory in 1976 with a few details below:
The same with an oval-section swing arm.
The return of the improved cantilever
The Cantilever is back, this time with a square tube manufactured by the Belgian company TILKENS, the same company that sold the Cantilever patent to Yamaha.
1978: The end of an era
Mick ANDREWS and the latest factory model in 1978, when he was no longer officially under contract with YAMAHA.
We move on to yellow, which foreshadows the colors of future Majesty models, and YAMAHA leads us to believe that it is abandoning the single shock absorber in order to knock out the competition with the TY mono in 1983.
