VELOCETTE MOV Models/Series Timeline, Specifications & Photos

In 1933, 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 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. The first of these new machines was the MOV, using a 250 cc engine of 'square' dimensions (68 mm bore and 68 mm stroke). It was an immediate sales success, having lively performance for the time (78 mph or 126 km/h), and proved a reliable machine with excellent road manners. From this machine, by lengthening the stroke of the crankshaft, the Velocette MAC 350 cc was introduced in 1934.
