Performance has earned a reputation for reliability pursuit that can never fail!
In the 1970s, Suzuki, a manufacturer of large motorcycles for export and other two-stroke engines due to exhaust gas regulations, urgently needed to convert to four-strokes.
Suzuki was the first of the four Japanese manufacturers to adopt a four-stroke engine, and its most important development themes were performance that was on par with or even better than that of other manufacturers, and above all, absolute reliability.
Then in 1976, two years after the Kawasaki Z1-Z2, the GS750 was released. At the same time, development of a 1,000 cc model to compete at the top end of the market was underway.
The air-cooled 2-valve DOHC 4-cylinder had one ball bearing and three roller bearings, the same as the 2-stroke models, for the crankshaft's main bearings, instead of the plain metal bearings that were common on 4-strokes.
For this reason, the crankshaft was assembled as a two-stroke, and the durability and wear resistance of the bearings with integrated balls and needles were unquestionably high.
When POP Yoshimura later approached Yoshimura to collaborate on a race tune-up, POP Yoshimura fell in love at first sight with the size of the margin and accepted the project with a resounding "yes" and this was the start of a story that has been etched in history.
