IMG_0452.JPGIMG_0459.JPGA good friend and rider is in possession of a BMW R90S - cafe purchased as a basket case that was located near Austin - Leander. It was advertised having the Pridmore engine from San Jose BMW on the MOA classified in the late eighties or early nineties. Delton had Ray Randolph of Midland Texas (he was a builder of the 10 gallon tanks for Perry's Sidecars) assemble it for him. They started it up and drove it, and it was very fast, but not ride-able on the street. It has been setting in an airport hanger covered with a tarp since. He would like to verify that it is a Pridmore, and also sell it.
It has a reinforced frame similar to the one pictured on the San Jose BMW website.
It has a reinforced swing arm that was made at San Jose BMW.
The motor has short cylinders typical of the Pridmore engines.
I am trying to gather information about these engines, and what if any provenance this setup has. The engine number shows it to have been based on an R90/6 The frame was powder coated after purchase and has the bracing typical of the San Jose racing frames. the front end is a stock non braced R90/S. It has flat slide Mikunis, and a nice 2 into one exhaust.IMG_0449.JPG
