Kawasaki stunned the motorcycle world in 2015 with the release of the track-only Ninja H2R, a supercharged superbike making 326 horsepower. The carbon fiber-clad bike remains the most powerful motorcycle on the market today, and now fans can build it with Lego set #42170. This detailed 1:8 scale replica features a two-speed gearbox, rotating four-piston motor, steering, and articulated suspension. When complete, the bike can be displayed on its kickstand.
