CCM 4 VALVE 500 MOTO CROSSER - A2 SIZE POSTER - NEW

The CCM 4 Valve 500cc moto crosser was released to much fanfare in the United Kingdom when released in 1979. In addition to the 500cc model 580cc 2 valve enduro models were produced plus Works Replicas with magnesium hubs, fork parts and lightweight engine covers.

The CCM frames were a work of art, the machines being the lightest, fastest and most expensive motocross machines available in the world at the time. The last BSA engine based machines were produced circa 1982

Clews Competition Machines (CCM) is a British motorcycle manufacturer based in Bolton, England. CCM was founded in 1971 by Alan Clews and, gained notability for producing specialised BSA powered motocross machines. The company has produced a variety of motorcycle models over its history using a variety engine suppliers including; Rotax, Suzuki and Kymco.

Alan Clews was a successful Trials and Scrambles competitor in the late 1960s. He wanted a lighter, more nimble and modern motocross bike, like the custom-built 500 cc motorcycles used by the BSA factory racing team.

Clews started building motocross bikes in his garage. Having no access to BSA works engines, Clews made his own extensive improvements to the standard BSA B50 500 cc engine, obtained by breaking up B50 MX bikes. His reputation grew as a builder of four-stroke motocross bikes that were capable of competing with the dominant two-stroke bikes. When the BSA Competition Department was disbanded in 1971, he saw his opportunity and bought all the old race bikes, factory parts that were available plus standard B50 engine spares.

In the mid-1970s, the CCM racing team achieved respectable results in the 500 cc Motocross World Championship, with rider John Banks placing in the top five several times.
