Losi Promoto-MX 1/4 Motorcycle RTR, Blue
Product Overview
The Losi Promoto-MX 1/4 Motorcycle RTR, Blue is a high-performance electric RC motocross bike designed to deliver a realistic two-wheel riding experience. Rather than using a conventional four-wheel RC chassis, the Promoto-MX combines electronic stabilization with a mechanical flywheel system to help the motorcycle balance, lean, and respond more like a full-size dirt bike.
This Ready-to-Run (RTR) model comes assembled with the radio system, motor, electronics, and servos installed. It features a brushless power system, motorcycle-style suspension, functional front disc braking, a realistic chain drive, and officially licensed motocross components.
Key Features
- 1/4-scale motorcycle design provides realistic dirt-bike proportions.
- Brushless 540 motor delivers strong acceleration and high-speed performance.
- 40+ mph potential top speed when equipped with the recommended 2S LiPo battery.
- Spektrum Smart DX3PM transmitter provides dedicated motorcycle controls.
- MS6X technology assists with electronic motorcycle stabilization and lean control.
- Integrated high-RPM flywheel contributes to realistic motorcycle dynamics.
- Functional front disc brake uses a cable-driven mechanism.
- Rear motor braking helps control deceleration.
- Rising-rate rear suspension provides progressively firmer resistance during compression.
- Adjustable front fork allows suspension tuning.
- Steel chain drive transfers power to the rear wheel for a realistic drivetrain experience.
- Dunlop Geomax MX53 tires provide authentic motocross styling and off-road traction.
- 3 mm aluminum plate chassis provides a rigid and durable foundation.
- Full ball bearings support smooth drivetrain operation.
- Blue factory finish and graphics give the motorcycle a distinctive motocross appearance.
Realistic Two-Wheel Control
The Promoto-MX is engineered around the unique dynamics of a motorcycle. Its MS6X electronic control system works with the motorcycle's mechanical flywheel to help maintain stability while riding.
The system assists with controlling the motorcycle's lean behavior, allowing riders to navigate turns and off-road terrain more naturally than with a conventional RC vehicle.
The result is an RC motorcycle that requires a different driving technique and provides a more authentic motocross-style experience.
Brushless Power System
The Promoto-MX uses a 540-size brushless motor powered by a 2S LiPo battery. Losi specifies a potential speed of 40+ mph with the recommended battery configuration.
A 2S 7.4V 5000mAh LiPo battery with an EC5 or IC5 connector is required separately, along with a compatible LiPo charger.
The brushless system provides the power needed for rapid acceleration and off-road riding while maintaining the scale-oriented motorcycle layout.
Motorcycle-Style Suspension
The Promoto-MX uses suspension components modeled after a real motocross motorcycle.
The front features an adjustable fork with spring and damping characteristics that can be tuned for different riding conditions. At the rear, a rising-rate suspension system provides softer initial movement and progressively increased resistance as the suspension compresses.
This arrangement helps the motorcycle maintain traction while providing additional support during jumps and harder landings.
Functional Braking System
The motorcycle incorporates a realistic front disc brake operated through a cable-driven piston and caliper mechanism. Rear-wheel braking is provided through the motor.
This setup gives the Promoto-MX a more authentic motorcycle feel and provides riders with additional control when approaching corners, jumps, and other obstacles.
Realistic Chain Drive and Tires
A steel chain transfers power to the rear wheel, reproducing an important mechanical feature of a full-size dirt bike.
The motorcycle also uses officially licensed Dunlop Geomax MX53 tires, which feature a motocross-oriented tread pattern suitable for off-road surfaces.
