LEGO® NINJAGO® Kai’s Motorcycle Speed Race (71838) is a 79‑piece set for builders aged 6+. Inspired by NINJAGO: Dragons Rising Season 3, it features two ninja motorbikes with rolling wheels—Kai’s red race bike with two golden daggers, and the villainous Spectral Dragonian Scout’s demon bike. The set includes two minifigures: Kai, armed with a translucent reveal blade and two golden katanas, and the Spectral Dragonian Scout with a sword. Kids can stage high‑speed good‑versus‑evil battles or display the bikes when not in action. Compatible with the LEGO Builder app for interactive building guidance. Age recommendation: 6+
