Ninja Battle Vehicle Tree House Showdown (LEGO 71857)

About this set

This is LEGO NINJAGO 71857, a 642-piece set rated 2/5 for difficulty and part of the DRAGONS RISING line. The centerpiece is a motorcycle with chunky tires and gold rims, built mainly in red, gold and black with blue and green accents, giving it a battle-ready look. Minifigures, a purple dragon and a blade round out the scene, so the whole thing reads as a standoff around the treehouse. For the build order, get the bike chassis and wheels together first, then add the gold rims and red bodywork; check that the big tires sit symmetrically so it doesn't lean. The purple dragon is fairly self-contained, so save it for last and set it up with the blade and minifigures. At 642 pieces and a 2/5 difficulty, it's an easygoing build for anyone comfortable with basic bricks. It suits NINJAGO fans who want a motorcycle with big tires and gold rims plus a purple dragon and minifigures to stage around it; if you only want the bike on display, the rest works as MOC fodder.
