MATCHLESS

500 MAG V-twin - 1914

Hemi-head pioneer

Brothers Charlie and Harry Collier were well-known in pre-WWI days for their racing exploits with JAP-engined Matchless bikes. In the 1910 Isle of Man TT, with the capacity of twin-cylinder machines cut to 680cc, Charlie's Matchless-JAP won at 50 mph.

Change of Engine

Eliminated from the 1911 Tourist Trophy by an Indian sweep, Charlie smashed all the American-held track records at Brooklands later that year. But for the 1913 Tourist Trophy, Matchless (founded by H. H. Collier in 1899) opted for a Swiss MAG engine, probably because the Geneva-based MAG company had just opened a British assembly plant at Willesden, North London.

Technically Advanced

The MAG "2C7-TT" racing engine was the most technically-advanced power unit of its day. Not only did it have overhead-valves when most of its rivals still had side-valves, but they were mounted in a hemispherical cylinder head, the first time this layout had been used on a motorcycle. The single carburetor was mounted between the cylinders, and the gear-driven Bosch magneto was located atop the gearbox. However, the three works racers failed to finish the 1913 Tourist Trophy, and in 1914, Harry Collier, well in the lead on the final lap, fell at Sulby half a lap from the end. Charlie had already retired, but Bert Colver, riding the third machine, finished in fourth place.
