Back then Yamaha were making a lot of 250 Road Race bikes, and a lot of this tech is off that ( certainly the reverse cylinder) , i guess they were trying to broaden the use of the R&D Yen..
I had heard about this, but never seen pictures, like a lot of bikes like this , sometimes you learn just as much from building something that doesnt work, than you do from something that does.
I raced an Ex-Factory Husqvarna 449 SM bike , that had the BMW motor, where the sprocket was on the swingarm pivot, i cant say i felt it was better , but it certainly wasnt worse.

People always be like: yeah, but it wasn’t better.
True, but they probably learned a lot trying things out.
Thanks for sharing.
So in front of the BMW brass during a race he threw his bike down , whipped it out & pissed on it !
Then he got what he wanted lol
that would just have to work, but so far, has not. Or maybe it just needed more development to get the rest of
the bike to work with it. Still love seeing people try different things.
Pointing to BMW as the nexus of this concentric-drive design failure ignores that it was an all-new built-in-Taiwan machine that weighed 10 lbs more than the heaviest of the competition and had vastly different design methodologies across the board than other dirt bikes.
That would be like pointing to Cannondale as proof that EFI on mx bikes is doomed to failure. It was not necessarily that feature that was problematic (although it may have been half-baked), it was the whole damn bike!
Pit Row
Are there more pics/info of that bike? If so please share!!
I sure would like to ride something like that, just to see what it feels like. Or even
one of those Horst Leitner dealio-s. I just think that sort of design stuff is so interesting.
