V-Twin Engine Building Blocks Overview
Build the Legend
The BR0015 recreates a classic retro cover-head "v twin" motorcycle engine. Use 846 precision ABS bricks to build every core component.
Assemble the cylinders, piston groups, and timing chain. This set is designed for adult mechanical fans and STEM learners aged 14+.
Powered Motion
Enjoy a hassle-free setup with no soldering required. Electric parts are built into factory modules. Simply follow the manual to fit the wiring.

Chain & Gear Linkage
The timing chain turns interlocking gear sets in sync. Watch the pistons reciprocate in rhythm, mirroring a real internal-combustion engine.
4 Speeds, Lights & Sound
Choose from four speed settings: idle, low, medium, and high. Synced engine sounds and indicator lights enhance the display presence.
Water-Mist Exhaust
A built-in atomizer creates a smoke-like mist from twin pipes. Use only clean water and avoid overfilling the tank.
Design & make
Architecture & Visibility
The iconic V angle layout stays faithful to retro designs. Black transparent covers expose the pistons and valves during the cycle.
Premium Materials
High-rigidity ABS ensures a firm clutch for repeated builds. Electroplated silver bricks provide a realistic metal finish for the exhaust.
