1922 Triumph SD Combination, 550cc


The SD (Spring Drive) was in fact a somewhat modernised version of the famous model H, which had grown out of the “Trusty” veteran Triumph. By the mid-twenties belt drive was losing its appeal to many motorcyclists, so Triumph designed a model with chain secondary drive. The primary chain is protected by a well-engineered aluminium case and runs in an oil bath to minimize maintenance of chain and clutch. The powerful 550 cc engine (bore x stroke =85x97) has lots of torque. The machine is equipped with three speed Sturmey Archer gearbox, 26x3 beaded edge tyres and Bosch magneto. There are a full acetylene lighting set and a rear view mirror board. The stylish sidecar is equipped with a windscreen.
