DouglasÂ 1928Â â SWÂ 5âÂ 498 cc flat twinÂ Â Â ohvÂ racerÂ Â Frame #TF194Â engine #Â EL362 When speedway racing arrived in Britain in 1928, the new sport quickly caught the publicâs imagination and before longÂ many majorÂ UK manufacturers listed a dirt track model, Douglas being theÂ first marque to establish dominanceÂ with its 500 cc DT 5 and 600 cc DT 6Â overhead valve models. The companyâs inline flat twins had benefited from much prior development on the Australian long tracks, but as shorter tracks became the norm in the U.K, the DTâs otherwise excellent handling could no longer compensate for the handicap of a longish wheelbase. Nevertheless, away from the speedway tracks, the DT in its less specialized âSWâÂ form proved a most competitive mount. âFor general racing work, the SW versions very also available at the same prices. These models differed only in the provision of brakes for both wheels, full mudguards, a silencer, a nearside footrest and a flywheel clutch. They were eminently suited for sand or grass, as the ever mounting list of racing successes showed. The additional equipment enabled them to be ridden to meetings without infringing the Road Traffic Actsâ ( From: Jeff Clew,Â âThe best Twinâ.) This powerful SW 5 is equipped with an improved clutch and brakes.
