Benjamin Grau 78 and 79

Many thanks to Stefan Gratz for these excellent shots.

In 1978 Mototrans, Joaquin Fargas raced at Mountjuic with a 860 ccm bevel B. Grau / V. Palomo. The crank cases were from the same batch of the Mike Hailwood IOM TT 78 engine with close engine numbers. To adapt a electronic Bosch ignition plate G. Pedretti cut and welded the original crank to modify (No. 38) for adaption.  In 1979 B. Grau together with S. Canellas started with a 950 ccm with a completely new and Bosch adapted engine casting (No.20). Please find some pics of both bikes at the Bikers Classic 2019 Spa Franchorchamps. If you like it please feel free for your Visitors Gallery.

Cheers Stefan.
