The automotive world hasn't seen a rotary engine in production since the Mazda RX-8 was axed in 2012. However, the Crighton CR700W is bringing it back in spectacular fashion in a machine billed as the "ultimate track bike."

In fact, the engine claims to have one of the highest specific power outputs of any naturally aspirated engine in the world. The dual-rotor mill displaces just 690cc, but generates 220 horsepower at 10,500 rpm (and 105 lb-ft at 9,500 rpm), which translates to 319 horsepower per liter. By comparison, the company says, most MotoGP race bikes make around 300 hp.

There are many advantages to a rotary engine. For one, it's extremely compact and needs fewer parts than a conventional piston motor, and the one in the Crighton is comprised of just three moving parts. Due to its simplicity, the entire assembly weighs just 53 pounds. Even with its six-speed gearbox attached, the unit comes in at just 95 pounds.

Combined with a Spondon-derived chassis made from 7000-series aluminum alloy and Dymag carbon fiber wheels, the entire CR700W weighs just 285 pounds. Even a Ducati Superleggera V4 tips the scales at 336 pounds, and it beats even the supercharged Kawasaki H2R in power per pound.

The sticker starts at £85,000 ($116,130)

I like everything but the sound coming out of the pipe.

I had the rotary pick up.  Power was great, gas mileage was terrible and at 30,000 miles the apex seals were toast.  Not a good experience.
