TheMatchless Silver Arrow was amotorcycle made byMatchless from late 1929 to 1933. It had a cast ironhead monoblockside-valve, 400 cc, 18°V-twin withchain drive, designed byracerCharlie Collier.[1]
The narrow angle of thecylinder bank'sV allowed the use of a one piece head, a practice used byLancia in itsearly V4 automobile engines.[2][better source needed] Therear suspension was a cantilever design using two springs and friction dampers beneath the saddle, very similar to the 1928Vincent HRD design. Linked brakes were used, as had appeared on the 1925Rudge Four. The carburettor was anAmal type 4/014 (bottom petrol feed).[3]
The bike did not sell well and within the year led to theBert Collier designedMatchless Silver Hawk.
Two models were produced, the 'Standard model' which had acetylene lighting and bulb horn, priced in 1930 at £57/10/6 and the 'De Luxe model' which had electric lighting and instrument panel, priced in 1930 at £63/2/6. In 1931 both were designated A/2 and minor changes included a four speed gearbox with improved gear ratios with lower 1st and higher top gear and a more rounded petrol tank, the Amal carburettor jet was changed from 70 to 55 and the diameter of the exhaust pipe was increased with ports on the head spaced further apart (65/8" instead of 51/8").[3]
