Saw a commercial for the new Mazda RX-8 tonight, which highlighted that brand's use of the Wankel Rotary engine. Hadn't thought about that engine in a long time and started wondering if any motorcycle company had ever tried using it as a power plant. You'd think the Rotary engine would be a natural -- no valves to adjust, fewer moving parts, less vibration (with counterbalancers), possibly better gas mileage, etc. Did a search and found out that it HAS been tried briefly by at least one (and probably more) company, Suzuki, during the mid 70s. Turn out the design didn't...
