Norton NRV588 rotary-powered motorcycle - Click above to watch the video
Undoubtedly, the company that's most often associated with rotary engine technology is Mazda. The Japanese automaker has been building Wankel powerplants for decades, with the current RX-8 standing alone as the only new automobile powered by the innovative engine architecture. In reality, though, many firms have experimented with the rotary engine, including Suzuki, which offered a rotary-powered motorcycle in the Seventies. Up until the mid-Nineties, European racetracks were filled with the buzzing sounds of Wankel-engined Norton motorcycles terrorizing their larger four-stoke twin-cylinder competitors and winning races such as the Isle of Man TT in 1992.
That unmistakable buzzsaw sound is set to make a comeback at this year's running at the Isle of Man as the latest Norton revival takes to the track. Click past the break for a video of the rotary-powered NRV588 as it makes a few laps at Donington Park and the dyno. Pay special attention to the exposed exhaust pipes, which reportedly get so hot they need to be made from Inconel.
