Since 1971 Bolton-based CCM have mostly operated under the capable stewardship of the Clews family; founder Alan Clews having been a successful off-road competitor in the previous decade.
Production of these hand-crafted machines now totals many thousands. albeit CCM are better known for MX than for Trials.
In 1972 Jack Mathews. successful 500cc moto-crosser. decided to ride sidecar trials. despite the prevailing fashion was for machines of 250/325cc. No matter. Jack bought Alan's personal 600cc MX machine. to which a sidecar was duly attached [see illustration on page 15 in Rolling Thunder by Bill Lawless; Willow Publishing (Magor)].
After 'softening' the engine. by now reduced to 500cc. Jack clocked some sensational results. winning 1973's ACU Sidecar Championship and finishing 2nd in that year's British Experts trial.
Despite competing on what was regarded as something of a 'dinosaur' Jack also scored a magical victory in the 1974 British Experts. believed the last major trophy to be gained by a half-litre 4-stroke.
Owned since 2007 by an arch BSSA enthusiast – who's fitted a new piston to the re-bored cylinder. and generally kept the famous combo up to scratch – YDB is presented in 'Ready for Scrutineering' condition. wearing the odd dent and scar with considerable pride!
V5C included.
