Suzuki's GT series, launched in 1972, marked a high point for the company's two-stroke technology. The lineup ranged from small twins to the iconic air-cooled 3-cylinder GT380 and GT550, but the flagship was the GT750. Nicknamed the 'Water Buffalo' in North America, the GT750 was Japan's first mass-produced, liquid-cooled motorcycle, making it a smooth and capable grand tourer.
Collectors appreciate the GT series for its unique character, especially the distinctive sound and feel of the 3-cylinder models. While the Honda CB750 and Kawasaki Z1 often get more attention, the GT750 offers a different take on the 1970s superbike with its torquey two-stroke power. The air-cooled GT380 and GT550, with their 'Ram Air' shrouds, also have a strong following for their blend of performance and style.
The market for Suzuki GTs remains accessible compared to its 4-stroke rivals. With an average sale price under $5,000, they represent a great value. Top-tier, professionally restored GT750s command the highest prices, but rideable examples and smaller-displacement models offer an affordable entry into vintage Japanese motorcycle collecting.
Buying Tips
- Exhaust systems are critical. The original multi-pipe exhausts are rare and expensive to replace, so check carefully for rust, damage, or aftermarket pipes.
- Listen for engine noises like piston slap or rumbling main bearings, which indicate a costly rebuild. Dried-out crank seals are a common problem on bikes that have been stored for long periods.
- On the GT750, thoroughly inspect the cooling system. Check the radiator for leaks or corrosion, as original replacements are nearly impossible to find.
- Prioritize a complete bike. Bodywork, badges, and chrome trim are very hard to source, making a basket case project much more expensive than it first appears.
- Check that the 'Ram Air' cooling shroud is present on GT380 and GT550 models, as they are often missing.
Prices for Suzuki GT models range from around $900 for projects to over $15,000 for concours-level restored examples.
