1/4 Losi Promoto-MX FXR 2S RTR Brushless RC Motorcycle
Description:
The Losi Promoto-MX isn’t just another RC motorcycle—it’s the first model to truly capture the complete experience of riding a real dirt bike. Designed for RC enthusiasts and motocross fans alike, it delivers unmatched realism, control, and excitement that has never before been achieved in a scale RC motorcycle.
Its authenticity goes far beyond appearance. While the narrow chassis, detailed rider figure, and officially licensed graphics look stunning, the real breakthrough lies in how the Promoto-MX rides. Losi engineered a unique blend of advanced electronics and mechanical systems exclusively for this platform, allowing it to mimic true dirt bike behavior with remarkable accuracy.
At the core of the Promoto-MX is a centrally mounted 2700Kv motor paired with a steel flywheel spinning at over 22,000 RPM. This creates powerful gyroscopic stability, keeping the bike balanced at speed. Complementing this is patent-pending Spektrum MS6X technology, which interprets your inputs through the DX3PM transmitter to precisely control leaning, turning, and wheelies with exceptional smoothness and realism.
Mechanically, the Promoto-MX is just as impressive. Its suspension geometry is inspired directly by full-scale motocross bikes. The rising-rate rear suspension enhances traction while minimizing bottom-outs on landings. Up front, the innovative fork design houses internal springs and damping that can be tuned with silicone oil and adjusted for ride height. A functional front and rear braking system dramatically improves stopping performance, reducing braking distance by nearly half compared to rear-brake-only designs.
The result is an RC motorcycle that performs exceptionally well at both low and high speeds. Dirt bike riders will immediately recognize the familiar handling feel, while RC car drivers will experience an entirely new style of driving—leaning through corners, clearing jumps, riding whoops, holding wheelies, and spraying roost.
At last, an RC dirt bike that truly delivers. Wherever you ride, the Losi Promoto-MX invites you to commit to your line, trust the machine, and become one with the bike.
