About LEGO Kai's Motorcycle Speed Race

Kai's ninja bike comes equipped with twin daggers and faces off against the Spectral Dragonian Scout's demon motorcycle in this 79-piece battle set inspired by season 3 of the NINJAGO Dragons Rising TV show. Both motorcycles feature moving wheels and distinctive designs that reflect their riders' opposing allegiances.

The set includes two minifigures: ninja warrior Kai and the villainous Spectral Dragonian Scout. Kai carries a translucent reveal blade and two golden katana swords, while his opponent wields a standard sword accessory. These weapons enable various combat scenarios as the characters clash in high-speed encounters.

Build and Play Features

Each motorcycle offers a different riding experience, with Kai's race bike measuring 4 cm high, 9 cm long and 3 cm wide. The demon bike provides an equally detailed alternative for the Spectral Dragonian Scout. The moving wheels on both vehicles allow for dynamic chase scenes and racing action.

Designed for builders aged 6 and up, this set encourages both solo play and group adventures where children can recreate scenes from the television series or invent their own ninja battles and racing competitions.
