Model 14 (Matchless G2) 248cc (70 x 65mm) ohv single || 340Ib || 75mph || 1958-66 || 85mpg

The 250cc learner laws meant many British manufacturers had a new market, and AMC came up with a new “lightweight” range. To do this they used a frame based on its James two-strokes and similar cheaper cycle parts, and designed a new four-stroke engine to fit. Engine appeared to be of unit construction, but the gearbox was separate and cylindrical, attached to the crankcases by a pair of steel straps, and you rotated it to maintain primary chain tension. These bikes were not a commercial success. They have their faults, not least build quality, but some find them attractive, especially those looking for a lighter, smaller machine. Best bets are AMC-forked versions, especially the late CSR (cafe-racer) versions.
