In 1972 Suzuki added a pair of air-cooled triples, the GT380 and GT550, to its range. The GT550's engine produced 50bhp at the crankshaft while the gearbox was a five-speeder, complemented by Suzuki's useful digital gear indicator in the instrument binnacle. There was also the luxury of an electric starter, something the smaller GT lacked. Performance was brisk, 110mph being achievable, but compromised by the fade-prone front drum brake, which was soon replaced by a single hydraulic disc. Smooth and comfortable, the GT550 changed only in detail thereafter in a production run lasting into 1977. This, a highly presentable Suzuki GT550 was imported from the US this summer specifically for this auction. All taxes have been paid, a NOVA declaration completed and the machine comes with US title so UK registration is straightforward.
