LOSI PROMOTO MX TECHNOLOGY INNOVATION 

REVOLUTIONARY

The summer of 2023 Losi brought one of the most unexpected and exciting rc product in years - The Losi Promoto Mx Motorcycle. At 1/4 scale the RC world had never seen before a motorcycle that had both the visual realism and technology so well harmonized and balanced. Motorcycle mechanics were executed nearly flawlessly with innovative electronics.

Combining Spektrum MS6X stabilizing technology that dramatically enhances balance and control with the gyroscopic force of the newly designed flywheel unit, the Losi Promoto Mx dirt bike immediately established a new precedent in the RC motorcycle genre.

As RC bikes of the past such as the Skyrc super rider SR5 1/4 or the Venom VMX 450 1/4 scale the gyro system was placed in the rear tire, which detracts significantly the functionality of the bike as well as defeats the realism of what a real motorcycle should both feel and look like. The development team at Losi ingeniously designed the Promoto Mx dirt bike with the Flywheel gyro system compactly mounted in the center of the frame that encompasses both performance with superb space management.

THE SWEET SCIENCE

In order to the take the RC motorcycle driving experience to a higher level and as never seen before in the industry, the Losi Promoto Mx dirt bike offers 3 ride modes: Dirt Mode, Street Mode, and everyone’s favorite - The Wheelie Control mode. With the Spektrum DX3PM transmitter included, these drive modes can be simply toggled in real time by switching with your thumb the A/B rocker control.

  • Dirt Mode - senses when the Promoto-MX bike pitches up past the threshold and clips the throttle output to avert wheel-overs and simultaneously, enables jumps and climbs by allowing adequate pitch without clipping the throttle.

  • Street Mode - clips the throttle immediately whenever it detects the Promoto-MX motorcycle begin to pitch upward, which allows acceleration to reach it’s maximum by forcing the front wheel downward.

  • Wheelie Mode - is guaranteed to bring smiles as the Promoto-MX bike displays exciting and epic wheelies on flat race tracks and parking lots at top speeds.

CHAIN DRIVE MECHANICS

Either on pavement or on dirt, the precise chain drive efficiently and dependably powers the rear tire with steel links made of 70 roller pins encircling 36-tooth sprocket hub made of aluminum and a 10-tooth steel drive sprocket. Realism is at the heart of the Losi Promoto Mx with this incredible and impressive chain drive mechanics.

REALISTIC DISC BRAKE

The front tires controls the majority of the braking action as in real motorcycles. The Promoto Mx front braking system utilizes caliper-operated brake pads and a steel rotor that is controlled by a drive cable and servo. This design allows for effective braking performance that dramatically reduces stopping distance.

INNOVATIVE LEAN BARS

One of the challenges in RC motorcycle vehicles is how to maintain an upright position in sharp turns, burn outs, and jumps without loosing control. The original Losi Promoto Mx lean bars have a freely rotating wheel at the end that spins smoothly to keep the RC bike upright without missing any action. It also is extremely effective regaining riding position in crashes by simply triggering the throttle.
