A 1:8 scale Technic build of the Kawasaki Ninja H2R, the supercharged track bike, in 643 pieces for ages 10 and up. It packs real mechanical features: working steering, suspension, a 2-speed gearbox, a 4-piston articulated engine and a turbocharger, plus a decorated windshield and Kawasaki logos on the tank. It is a display-and-play model, not a remote-controlled toy, so it suits builders who like seeing how a motorcycle works. Against simpler Technic bikes it is denser and more detailed, and owners rate it highly for the build and the finished look.

Owners rate it highly, praising the detailed build and the working steering, suspension and gearbox. Many say it looks great on display and is a good step up for older kids. A few find the build fiddly and the functions more showpiece than playable.
The LEGO Technic Kawasaki Ninja H2R Motorcycle (42170) is a 643-piece building set for ages 10 and up. It recreates the Kawasaki Ninja H2R, one of the fastest production motorcycles in the world, at 1:8 scale.
The model has steering, suspension, a 2-speed gearbox, and a 4-piston articulated engine with a turbocharger. The windshield element has custom decoration, and the Kawasaki logo appears on both sides of the fuel tank.
Builders can play with the different functions, then use the kickstand to display the finished model. The LEGO Builder app lets builders zoom in and rotate models in 3D and track their progress.
