Additional photos of this 1972 Suzuki GT750 are available here for your perusal.
When Honda released the CB750, other Japanese manufacturers had no other choice but to respond. Kawasaki made the choice to develop a little bit more power than the CB750 with the Z1, but Suzuki chose to stay with their specialty of two-strokes and in 1972 they released the GT750.
The prototype Suzuki GT750 was shown at the 17th Tokyo Motor Show in October of 1970 and launched in Japan in September 1971 as a sports tourer. Developed from the Suzuki T500 with an extra cylinder and liquid cooling, it was marketed as the Le Mans in the US and Canada. Looking at the success of the 4-cylinder 4-stroke engine, it was actually pretty bold from Suzuki to keep their 2-stroke engine. But the major innovation Suzuki added to their machine was liquid cooling, which lent itself to the international nickname of “Water Buffalo”. Indeed, the GT750 was the first mass production bike from Japan that featured it.
With its dry weight of 507 lbs, the bike could reach about 110mph. It had a double-sided, twin-leading shoe, 200 mm drum front brake with 180 mm drum rear. The Exhaust Coupler Tube System (ECTS) that connected the left and right side exhausts together was designed to boost low-end torque. Carburetors were 32 mm Mikunis and power output was 67 bhp at 6,500 rpm. The two-stroke engine had a strong flat torque curve producing useful drive from as little as 2000 rpm and provided a more sophisticated ride than its peakier H2 rival. Also included was Suzuki’s SRIS (Suzuki Recycle Injection System), a method minimizing smoke by burning oil/gas lying in the bottom of the crank chambers – a first for any two-stroke from any manufacturer.
The cylinder block was alloy with cast iron liners. It had a five-speed gearbox and three into four exhaust. The ride was most impressive when the GT was used in a touring function, being able to cruise at high speed in relative comfort. Enthusiasts yearly gather at events to show off their pride and joy, and also to celebrate Suzuki’s first big 750cc success, this bike was the beginning of Suzuki’s love affair with the 750 class.
The seller of this example (VIN: GT750-18464, Engine #: GT750-18495) acquired it five years ago from a fellow collector. During that time it’s only ridden it twice – once “for a few kilometers around the block by my brother” and again recently to verify that it would run before listing it here on Iconic (video above).
The seller states that this Suzuki “presents as an immaculate bike for its age and could easily stand on show with no problem. Albeit said it is a great display bike, when I took it out and fueled it up, the bike started up with relative ease.”
