GL750 4 cylinder 2 stroke prototype

[pipe welder]

Displayed in 1971 by Yamaha - Sadly never reached the production stage.

I've never seen this before!



The engine had in it already the ideas and design for the mighty Yamaha TZ700,/TZ750 which would be introduced in 1974. The TZ750 was the most winning two stroke race engine ever..

The Yamaha GL750 4 cylinder 2 stroke prototype which was displayed on the 19th Tokyo Motorshow in November 1971 was the ultimate bike

Can you imagine the fun, accelerating this Yamaha GL750 from the traffic lights leaving all car-drivers with wide open mouths and in a blue haze of lovely stinking two-stroke smoke........! Environmentalists were not invented then.....!

I actually remember this prototype.

Yes.

I'm that old.




I think it was the "cover bike" on a magazine "back in the day".

[H2 Dude]

I think it was Cycle Guide that had a write up on this bike.brief as it was spotted on the track being tested..EPA I think killed it

Reminds me of a Suzuki GT750

But it probably would have been badass to ride

[JA-Moo]

Both the Kawi 4 and the Yamaha were directed towards "touring", so I doubt either one would been a good performance candidate. With out a lot of work, like the Suki GT 750.

Certainly the exhaust doesn't look like it was performance minded.
