Antig-Jawa 500cc Grass-track Racing Motorcycle
The sports of speedway, grass-track, and long-track racing are closely related, the principal differences being the composition of the track surface and the length of the circuit, long tracks typically being 800-1,000 metres in length compared to around 400 metres or less for a speedway venue. The machines too share many basic characteristics, though long trackers are lengthier and have two-speed gearboxes and different, longer-travel front suspension. With their much longer straights, long tracks allow for significantly higher speeds. Long track engines will, generally, be tuned for greater top-end power to take advantage of these long straights.
Just as in speedway, the JAP engine ruled the roost in long track's formative years, before the Czech-built Jawa/ESO began to assert itself in the early 1960s. In turn, Jawa's dominance of both speedway and long-track racing would be challenged by the four-valve Weslake engine, and Jawa responded by introducing a new double-overhead-camshaft, four-valve motor in the late 1970s. Available in speedway/long-track variants as the Type 894/895, this engine was adequately powerful (producing up to 65bhp) but rather top heavy, and was superseded by the more compact, single-overhead-camshaft Type 896/897, this being the final development of Jawa's classic upright single. This four-valve Jawa engine and gearbox are installed in an Antig frame, the machine being presented in restored condition. There are no documents with this Lot.
