Yamaha GL750 Prototype
The Yamaha GL750 4 cylinder 2 stroke prototype which was displayed on the 19th Tokyo Motorshow in November 1971 The Yamaha GL750 (codename YZ 401) sadly never reached the production stage. The engine had in it already the ideas and design for the mighty Yamaha TZ700,/TZ750 which would be introduced in 1974. Actually the crankcases were taken from the YZ648 (TZ700 Prototype). The cycle parts were very similar to the production machine TX750 and shared with the Yamaha Rotary RZ201.
The two-stroke injection system was also a prototype item for snowmobiles....! Many journalists at that time wondered if that engine ever turned its crankshaft
