Description:

The Losi® Promoto-MX is not just another scale RC motorcycle — it’s the first RC bike that truly delivers the sensation, control, and excitement of riding a real dirt bike. Designed to fulfill the long-standing dream of RC enthusiasts and motocross fans alike, the Promoto-MX sets a new benchmark in realism and performance.

Its authenticity goes far beyond appearance. While the narrow frame, rider figure, and officially licensed graphics are impressively detailed, the real breakthrough lies in how accurately the Promoto-MX replicates true dirt bike dynamics. This is achieved through a groundbreaking combination of mechanical engineering and advanced electronic technology developed exclusively for this platform.

At the core of the Promoto-MX is a centrally mounted brushless motor paired with a high-RPM steel flywheel. Spinning at over 22,000 RPM, the flywheel generates gyroscopic stability that allows the bike to remain balanced at both low and high speeds. Spektrum’s patent-pending MS6X technology interprets your steering and throttle inputs from the DX3PM transmitter, enabling smooth leaning, precise turning, and controlled wheelies with unmatched realism.

Mechanically, the Promoto-MX mirrors full-scale motocross suspension design. A rising-rate rear suspension enhances traction while preventing harsh bottoming on landings. Up front, an all-new fork system with internal spring and damper allows ride-height adjustments and tuning via silicone oil changes. Braking performance is equally authentic, featuring functional front and rear brakes that significantly shorten stopping distances compared to rear-brake-only systems.

Together, these mechanical and electronic innovations allow the Promoto-MX to outperform any RC motorcycle before it — delivering confidence, control, and realism at any speed. Whether you’re carving berms, clearing jumps, holding wheelies, or throwing roost, the Promoto-MX delivers an immersive riding experience that feels instantly familiar to dirt bike riders and entirely new to RC drivers.

This is more than an RC bike — it’s a riding experience. Grab your Promoto-MX, choose your line, commit, and become the bike.
