But some suppliers will talk-a little. Mike Parker, vice president of business and corporate development for Ontario-based Revolution Rotary Engines, says, "We have certainly looked at motorcycles as a viable product. We could, for example, provide a more practical hybrid engine than a larger conventional four-cylinder engine. This can translate well for motorcycles. A rotary has far fewer moving parts, is lighter and smaller, has a superior power-to-weight ratio, is more fuel efficient and offers more bike-design possibilities." Parker cites a single-rotor, 35- to 45-hp unit that displaces 294cc and weighs 33 pounds (block alone) as an engine that could be a nice fit for motorcycle application.
