CCM Motorcycles was a British motorcycle manufacturer, located in Bolton, England. Alan Clews formed CCM (Clews Competition Motorcycles) in 1971 from what was left of BSA's off-road department and bought spares to produce his own motocross motorcycles.


The Bolton factory  soon became a well established successful business.


In 1977 Sammy Miller approached  Clews to build a 4 stroke trials engine, whilst it was possible it wouldnt be financially viable to do it. With this in mind Clews knew he could not just rely on motocross so why not build a trials machine ? 


The project began in 1978  when he hired  Nick Jefferies the Yorkshire man from over the hill to be his development rider. Nick had loads of knowledge and experience with the 4 stroke factory Honda machines.


First job was to make a frame for the BSA engine which would be 343cc  using a mixture of BSA engine parts. Like most manufacturers, measurements would have been taken from a few current bikes at the time. Look at the very first Italjet it pretty much used a Bultaco frame.  


The first bike was ready to ride early 1978 in February. After various testing, trials and modifications for Nick Jefferies, Alan decided to put the bike into production. 


In total 105 bikes produced , they went on sale in September 1978 and sold out in 4 months !

Was the British 4 stroke about to make a return?


The price approx £1300  in 1978 , some 37 years later you see them advertised for £9000 upto £11500 amazing , but i always wonder what they sell for? You can ask what you want for a bike right !


The bike had Marzocchi forks, Marzocchi rear shocks , grimica hubs, brakes pretty much the best at the time, 24mm Amal 



Nick  Jefferies left CCM to concentrate on his road racing career of which he would go on to win the famous Isle Man TT in 1993 , this was after 8 second places!


Alan never produced another batch of bikes and by the end of 1979 the project had finished ..............
