Does anyone remember Dr Joe Erlich and his ideas for different engine development ?

He was the one who brought the Rotax engine into the motorcycling world some 20+ years ago, with Chris Grose (a Manxie) being one of the development riders way back in the early 80's. ( A Link to Chris's experiences are below)

Didn't Con Law ride a bike with a derivitive of his engine in TT in the early 80's ?

I remember a few years ago, some kind of agreement with Brabham (I think), for a variable capacity engine that he was working on. Can't remember exactly how it worked, but with the flick of a lever, the engine capacity could be altered from 250cc to 300cc, or was it even higher ??

A brilliant mind and such a genius, that sadly is no longer with us.
