(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
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!”
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
WHAT THEY COST
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.
WHAT TO LOOK FOR
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.
