The K series was expensive to produce, requiring selective hand assembly of the shaft-and-bevel camshaft drive; it was determined that a simpler OHV design would be quicker to build and require less skilled labour to assemble and so the company decided to introduce a new line of [[overhead valve]] (OHV) machines, in order to cut production costs and make a more affordable motorcycle. The first of these new machines, in 1933, was the MOV, using a 250&nbsp;cc engine of 'square' dimensions (68&nbsp;mm bore and 68&nbsp;mm stroke). It was an immediate sales success, having lively performance for the time ({{convert|78|mph|disp=or|abbr=on}}), and proved a reliable machine with excellent road manners. From this machine, by lengthening the stroke of the crankshaft, the [[Velocette MAC]] 350&nbsp;cc was introduced in 1934. It proved even more popular than the MOV, and became a real money spinner for the company, bringing much needed capital into the firm. In 1935 an entirely new machine was introduced, based on the two previous OHV models, the [[Velocette MSS]] of 500&nbsp;cc. A new, heavier frame was fitted, with the intention that the machine could serve as a sidecar hauler. This new frame was developed from the MkV KTT racing machine, and was shared with the KSS MkII of 1936&ndash;1948. The MSS also proved very popular and profitable for Veloce.<ref name="Mirco" /> A 350 cc version of the MOV was the basis for the company's World War II military motorcycles.<ref name="siegal thruxton" />
