1975 Suzuki RE5

Suzuki had high hopes for its RE5 Wankel-engined bike launched in 1975. It had started looking at the Wankel engine in the mid-60s and bought the licence to the concept in 1970.
Apparently all of the big four Japanese makers experimented with the design, Yamaha even showing a rotary-engined bike at a motor show in 1972. But Suzuki was the only one of the big four to go into production. Like many others at the time, Suzuki believed that the light, compact, free-revving Wankel design would consign piston engines — with their complex, multiple, whirring valves and pistons, which (can you believe it?) had to reverse direction all the time — to history.
