Most Expensive Motorcycles
1) 1927 Zenith-JAP 8/45hp
US$319,653 (sold for £177,500) September 2008
London, U.K.

The combination of a Zenith-JAP motorcyle and an AJS-produced Graiseley TT Model 259 racing sidecar dating from Zenith’s heyday was purchased new from Blay’s of Twickenham in April 1927 by Roland Martin. There are original bills of sale for both the motorcycle and sidecar on file. Roland Martin was one of the few private owners who had their own workshop at Brooklands and prepared and tuned other people’s machines for racing. Rallies were his first interest, but he preferred motorcycle combinations and the KTOR-powered Zenith was one of the most desirable machines for £140 in 1927.
