If you've never heard the Crighton CR700W with its 690cc rotary twin motor, then you probably think you've heard the nicest-sounding engine ever, but you haven't. And it's not just the sound of the CR700W that makes it special because quite literally everything on this bike is special, and an absolute demon around a track.

The only problem with this bike is that only 25 were built, but the 15th model produced is now up for sale, and it only has 124 miles on the clock.

The whole bike is dripping in carbon fiber, giving it a dry weight of only 285 lbs and a frankly ridiculous output of 220 HP delivered at 10,500rpm and 105 lb-ft of torque at 9,500rpm. Since this is just a 690cc twin, that amounts to 319 HP per liter, which is more than MotoGP bikes from not so long ago. So bags of power in a unit that doesn't weigh much more than a motocross bike, but every other aspect of the CR700W is equally as mind-blowing.

Brembo GP4-MS 108mm calipers take care of all the braking, while Ohlins FGR 300 front race forks, and a new top yoke to allow for the new forks, ensure that when you bite down on the Brembos, the CR700W will stay composed.

What do you think?

The underseat exhaust itself is a work of art and shaped like a Wankel rotor, and when it fires up, you quickly realize the size of the can isn't just for show—it roars. Just listen to Guy Martin ripping one of these models around a track.

When new, the Crighton CR700W cost £95,000 ($127,048) if you were lucky enough to get one of the 25 units. Since their production, the CR700W has only appreciated and this particular model is up for £154,495 ($206,614). The CR700W is arguably the ultimate track weapon and if it sells for its asking price, the owner will essentially have made $80,000 and got to spend around three hours on one of the rarest bikes in the world—finally, a bike that actually made good financial sense to buy.
