Losi 1/4 Promoto-SM FXR Supermoto

1/4 Promoto-SM FXR Supermoto Motorcycle RTR Basic, White

The Losi Promoto-SM delivers the most realistic supermoto RC riding experience ever created. Engineered for asphalt, concrete, and hard surfaces, it combines advanced electronic control with true motorcycle-style mechanics for unmatched stability, balance, and responsiveness.

With a 2700Kv motor spinning a high-RPM flywheel, the Promoto-SM uses gyroscopic force and Spektrum MS6X technology to lean, carve, and wheelie just like a real bike. Updated street-ready components including Pro-Line SM tires, a stronger front brake, and new lean bar wheels give it exceptional traction, stopping power, and cornering ability.

Visually, it mirrors a real supermoto with FXR-licensed graphics, hand guards, a short front fender, and a detailed rider. From rising-rate suspension to cable-driven front disc brakes, every detail enhances realism. With 40+ mph speeds and multiple drive modes, the Promoto-SM is the closest you can get to riding a real supermoto — in RC form.
