c.1970 Greeves-BSA 441cc Special
Frame no. 56 0179
Engine no. B44R 1572
One man's idea of the perfect off-road motorcycle, this unique machine combines the four-stroke slogging power of a BSA B44 motor with a lightweight Greeves Griffon chassis. Introduced in 1969, the Griffon was the culmination of Greeves' long line of successful moto-crossers and came in 246cc and 380cc variants, the two-stroke engine being a development of the preceding Challenger's. Frames were constructed in Reynolds 531 tubing and equipped with a Ceriani-type Metal Profiles front fork and conical alloy hubs. The engine is from a Victor Roadster dating from circa 1967. Displacing 441cc, the Victor's power unit was developed directly from the works 420cc moto-cross engine, itself a distant cousin of the first of the line that had debuted in the humble C15 250 roadster back in 1958. Of rather less exotic specification than that of the Grand Prix moto-crosser, the Victor Roadster's de-tuned engine employed a linered cylinder and the same camshaft as the SS80 roadster. Unfortunately, not a great deal is known of the history of this fascinating special other than the fact that it was constructed by Hawaii motorcycle dealer, John Ledyard, originally from Whitefish, Montana. Offered on a bill of sale.
