Calling it a motorcycle is a little disingenuous, since it's really a roadster — but with only three wheels, the Polaris Slingshot Motorcycle is actually a bit of both. Powered by a 2.4L engine, this two-seat open-air vehicle sits just inches off the ground, with a 5-speed manual transmission and lightweight polymer body panels to create an exhilarating motoring experience. You might have to get your motorcycle license to drive it — depending on local laws, — but the first time you round a corner at speed, it'll be well worth the effort.
Building on the success of their racing-focused Atom, the chaps at Ariel have turned their attention to the two-wheel market. The Ariel Ace Motorcycle is the stunning result. Sporting a skeletal frame that recalls the Atom but is machined entirely from an aluminum alloy billet, this sporty bike is powered by a 1237cc, water-cooled Honda engine good for over 170hp, a top speed of 165mph and a 0-60 time of just 3.4 seconds. Beyond the specs, though, the Ace is incredibly customizable, sporting your choice of seats, handlebars, exhausts, brakes, tank sizes and styles, and front ends, with the promise that your entire cycle will be built by a single technician who signs his work when he's done.
The Kawasaki Ninja250 is a fine bike all on its own, but if you yearn for something a bit more unique, this Brasse 31BLK Kawasaki Ninja Mod Kit should do just fine. The first production mod kit for the Ninja250, it comes complete with two gullwing headlamps, a drag speedometer, a new rear fender assembly, right & left component/cover panels, plus options like a quick-release passenger seat, replacement right and left lower fairings, and a side-mount license plate bracket. But the best part? It also includes all the necessary tools in the kit, so you can transform your bike from the comfort of your garage.
