The first machine to bear the name 'Velocette' was a two-stroke, so called to differentiate it from the larger, four-stroke Veloce model, and the type was an almost permanent fixture of the Hall Green range up until WW2. The ultimate expression of Velocette's two-stroke line - the GTP - appeared in 1930. Unlike many of its contemporaries, the GTP was not a 'built-to-a-price' utility model but a sporting lightweight of advanced design incorporating coil ignition and pumped lubrication controlled by the throttle. Early models had the three-speed hand-change gearbox, later ones the four-speed foot-change type, and all employed the characteristic slim-line Velocette clutch.
