Losi Promoto-MX - The Ultimate 1/4 Scale RTR Experience
MS6X Stabilization. Functional Front Brakes. Rising Rate Suspension.
The Losi Promoto-MX isn't just a remote-controlled motorcycle; it's a breakthrough in RC technology. By combining mechanical realism with electronic sophistication, the Promoto-MX captures the "soul" of motocross. From blitzing through whoops to airing it out over triples, this 1/4 scale powerhouse delivers an authentic "braap" experience that will satisfy both dirt bike fans and RC car enthusiasts alike.
Advanced Suspension & Dual Braking System
Losi's development team meticulously studied full-size motorcycle geometry to create a rising-rate rear suspension that provides superior grip and prevents bottoming out. Up front, the tunable fork design handles terrain with precision. Most impressively, the Promoto-MX features an innovative front and rear wheel braking system, utilizing a cable-driven front disc brake to cut stopping distances in half and allow for more aggressive racing lines.
Patent-Pending MS6X Technology
Balanced control at any speed. The Spektrum MS6X technology allows you to carve tight berms and hold wheelies with unprecedented stability, adjustable right from your transmitter.
High-RPM Flywheel
The frame-integrated flywheel provides the gyroscopic force needed to keep the bike upright over jumps and through the roughest rhythm sections.
