Suzuki GT550 model history
1972�1977

Suzuki introduced a trio of three-cylinder two-strokes in 1972: the air-cooled triples GT380 and GT550 and the new flagship, the liquid-cooled GT750. Both of the air-cooled models featured Suzuki new patented Ram Air cooling system that forced cool air under a aluminum shield mounted on the top of the cylinder heads and improve cooling. The system really worked and the GT models didn't suffer from the problems that usually are attached to air-cooled two-strokes: overheating engines and loosing power as a result of it. According to the test rides from those days the GT380 and GT550 delivered the same amount of power even after hard use. You can read more of the Ram Air Cystem on a GT550 road test, published in Cycle World, Jan 1973.

The GT380 had six gears but the GT550 with its wider power range worked just fine with its 5-speed gearbox. The GT550 (called Indy in the USA). The model was sold until the introduction of four-stroke GS550 in 1977.

Did not work so well my 74 kettle always picked up in the centre bore.
74 Kawasaki H1E , far faster and fun.
