The third of Velocette’s overhead-valve, high-camshaft, single-cylinder designs. The MSS model was first produced in 1935, and was the third of the M-series of overhead-valve singles which included the MOV, MAC, Venom, and ultimately the Thruxton, all of which featured the high-camshaft layout.

The first of these new models had been the 250cc MOV of 1933, which was joined for 1934 by a long-stroke 350cc version – the MAC. In creating the MSS, Veloce kept to the basic design, combining the MAC’s 96mm stroke with a larger bore to create its new ‘500’.
The MSS engine went into a new frame derived from that of the racing KTT. The model disappeared from Veloce Limited’s range in 1948 while the company concentrated on the LE, reappearing in 1954 with a new swinging-arm frame and Hall Green’s own telescopic front fork.
