1974-1976 498cc liquid-cooled single chamber rotary, 62bhp, 230kg
What is it? The result of Suzuki’s dalliance with a technical cul-de-sac that was rapidly killed off by the sharp rise in the cost of fuel and the fact the firm’s other less complicated offerings were better in every respect.
Why so odd? Neither a two-stroke nor four-stroke but delivering elements of both, the wankel motor can produce massive performance, especially in a light bike. But the RE5 was big, heavy (a gargantuan 230kg dry), thirsty and no match for Suzuki’s more conventional GS750.
Why you want one: Like a factory turbo, own one for the sheer hell of it. Those who own RE5S, love them. Plus there will never be another Japanese rotary.
