True Motocross ThrillsRevolutionizing the Scale RC Motorcycle Experience

Experience authentic off-road action with the Losi 1/4 Promoto-MX Motorcycle RTR, the first scale RC motorcycle that accurately reproduces the true feel and performance of riding a real dirt bike. Engineered with innovative Spektrum MS6X technology and a frame-integrated high-RPM flywheel, this brushless RC dirt bike delivers unmatched electronic and mechanical balance on any terrain. Whether you are carving berms, holding long wheelies, or reaching speeds over 40 mph, the Promoto-MX brings unmatched realism to your drive.

Engineering Meets AuthenticityUnrivaled Mechanical and Electronic Off-Road Performance

The Losi 1/4 Promoto-MX Motorcycle RTR combines groundbreaking electronic innovation with true motocross mechanical engineering. Powered by a centrally mounted 2700Kv brushless motor spinning a heavy steel flywheel at over 22,000 RPM, it creates incredible gyroscopic stability to handle high speeds and sharp turns with ease. A rising rate rear suspension system, paired with a tuneable internal-spring front fork and cable-driven front disc brakes, cuts stopping distances in half and prevents bottoming out on big landings. Completely detailed with officially licensed FXR Racing graphics and high-traction Dunlop MX53 tires, this ready-to-run RC bike offers a thrilling driving experience for RC enthusiasts and dirt bike lovers alike.
