Dubbed 'Manx Grand Prix' in 1939, what would become the best-known racing motorcycle of all time had become simply 'Manx' when production resumed in 1946, though only the presence of Roadholder telescopic front forks distinguished the post-war bike from the '39 version. The first significant change in engine specification occurred in 1949 when a works-type double-overhead-camshaft cylinder head was adopted, but the major development was the arrival for 1951 of the peerless Featherbed frame. Manx engine development continued steadily until production ceased at the end of '62, the most significant design change being the adoption of 'square' bore and stroke dimensions for 1954 and coarser-pitch bevel teeth in 1957.
An older restoration, since deteriorated, this 500cc Manx has clearly not been used for a considerable period; accordingly, the machine will require careful recommissioning, or possibly more extensive restoration, before further use and thus is sold strictly as viewed (the engine turns over but only one gear selects). Prospective purchasers must satisfy themselves with regard to the condition, completeness, authenticity and compatibility of this Lot's component parts prior to bidding. It should be noted that there appears to be evidence of another engine number stamping. Notable features include a Lucas competition magneto; Jaeger 8, 000rpm rev counter; and a Tommaselli throttle. Offered with a photocopied technical article only.
All lots are sold 'as is/ where is' and Bidders must satisfy themselves as to the provenance, condition, age, completeness and originality prior to bidding. Visit the Bonhams Motorcycles website for all pertinent auction information.
