The Revolution in RC Two-Wheeled Performance
The Losi Promoto-MX isn’t just another RC vehicle; it's the first scale 1/4 dirt bike that accurately reproduces the full experience, high-flying action, and physics-defying fun of riding a real motocross bike. Fulfilling the long-awaited dream of RC hobbyists and dirt bike fans alike, this machine pairs a beautifully detailed, narrow chassis and officially licensed Pro Circuit graphics with a revolutionary hybrid of mechanical and electronic stabilization.
Patent-Pending Spektrum MS6X Technology & Flywheel Stability
At the heart of the Promoto-MX's uncanny balance is a high-RPM flywheel system integrated into the center of the frame. Spinning at over 22,000 RPM via a 2700Kv brushless motor, it creates a massive gyroscopic stabilizing force. This works in perfect harmony with patent-pending Spektrum MS6X technology, which continuously monitors lean angles and gravity vectors to translate your transmitter steering into fluid, realistic cornering, carving berms, and skimming whoops without washing out.
Scale Motocross Suspension & Dual-Wheel Braking
Losi’s development team closely studied full-size motorcycle geometry to deliver authentic off-road handling. The front forks feature an internal spring and fluid dampener that can be custom-tuned with silicone shock fluid, while the progressive rising-rate rear suspension provides unmatched traction and prevents bottoming out on harsh flat landings. To slow things down, a functional cable-driven front disc brake combines with electronic rear motor braking to slice stopping distances in half.
Pro Circuit Combo — Fully Ready to Ride Out of the Box
This premium combo version features officially licensed Pro Circuit racing graphics and a realistic rider figure suited up in authentic fabric apparel, a detailed helmet, and goggles. Unlike standard base models, this special combo pack comes fully loaded from the factory with a high-capacity Spektrum Smart G2 2S LiPo battery, a convenient Spektrum Smart S120 USB-C charger, and even the four AA transmitter batteries. Just charge up and get ready to throw massive roost!
Note: The included Spektrum Smart charger requires a standard USB power supply block/wall adapter (sold separately) to plug into a power outlet.
