Good Gravy

The well-known and much admired alloy racing Gold Star engine (see also Lot 9) was a very versatile power plant and could be bought in several different versions, including a very staunch scrambler, the 500cc Catalina. A very successful competition bike, the 1961 Catalina scrambler offered a full race cam, larger carburettor, and a reverse cone exhaust to deliver full power over a wide rev range. Add to this a lightweight frame and high ground clearance and you have one very cool dirt bike that established first principles for all future high powered off road designs. This wonderful example has been restored immaculately by Graeme McCosh and, since then, has resided in a private museum.
