CCM (Clews Competition Machines) was founded in 1971 out of the collapse of BSA’s competition department. Alan Clews, founder of CCM, was a successful trials and scrambles rider in the late 1960s. He wanted a lighter, more nimble and modern motocross bike, like the BSA factory-engined 500cc works specials. When the BSA competition department went out of business, Clews saw his opportunity and purchased all the works parts and started building motocross bikes in his garage. As the BSA works parts ran out, he started developing his own parts, and his reputation as a builder of motocross bikes grew.

When Cycle World tested the 1973 CCM 600MX, they said, “The CCM is the most powerful motocross four-stroke single we have ever tested! With a bore of 90mm and a stroke of 95mm, the torque is almost too much for the average rider. The quality of the nickel-plated frame is on par with the Rickman’s, and with a dry weight of 230 pounds, it is lighter than many of the open two-strokes!”

Note: Dan White of White Brothers fame purchased Cycle World’s CCM in 1974.The pictured example is a brand-new, never-ridden 1976 CCM 600MX with a four-speed transmission. The triple clamps, fork sliders, hubs, backing plates and engine covers are manufactured out of cast magnesium. In 1976, with Brits Vic Allan, John Banks and Vic Eastwood riding for them, CCM finished second, fourth and fifth in the British Motocross Championships. Vic Allan even finished third in the Grand Prix of Finland and Luxembourg.

After ceasing operations in 2004, CCM is back in business and has even tried to field GP and British National race team over recent years.

1976 CCM 600MX FACTS


CCMs were the most expensive bikes of their time at $4000, which was almost double any other European brand. MXA‘s featured bike, owned by the Early Years of Motocross Museum, is valued at $20,000.

In 1976, customers could purchase a CCM with a 500cc or 600cc four-speed engine, or a 635cc model with a three-speed transmission. All machines were for motocross only.

Look for lots of magnesium and a beautiful nickel frame. Tanks were either fiberglass or aluminum, and the fenders were by Preston Petty. The footpegs were bolted directly to the engine covers.
