Immerse yourself in the world of radio-controlled modeling with the Losi 1/4 Promoto-SM FXR Supermoto { {14da5356856252c43b1d7a1909aa4dfc}}, an RC motorcycle with exceptional performance. Thanks to its innovative technologies, realistic supermoto design, and impressive power, it transforms any paved surface into a real race track.
With a top speed of over 40 mph, a high-performance brushless system, and Pro-Line Supermoto tires, this bike excels on hard surfaces such as concrete, asphalt, and bitumen. The patented MS6X Spektrum system guarantees unparalleled control and stability.
Unmatched realism: an RC motorcycle that looks like the real thing
- Pro-Line Supermoto tires: These specially designed tires offer exceptional traction on hard surfaces such as asphalt, concrete, or parking lots. Their durable rubber compound ensures excellent grip even during sharp turns or sudden braking.
- Official FXR graphics: Dressed in durable, high-quality vinyls, the Promoto-SM features an officially licensed design that perfectly mimics the aesthetics of full-size supermoto bikes. Visual details, such as hand guards and a shortened front fender, reinforce the model's authenticity.
- Realistic rider figure: The rider, with its rubberized plastic exterior and detailed FXR racing gear, is not only aesthetically pleasing but also functional. Its durable design allows it to withstand impacts while maintaining a pristine appearance.

Advanced technology for optimal performance
- Integrated flywheel for gyroscopic stability: The steel flywheel, rotating at 22,000 rpm thanks to the brushless 2700Kv motor, stabilizes the bike in all circumstances. This allows for more precise cornering, controlled wheelies, and better responsiveness on uneven surfaces.
- Spektrum MS6X system: This patented technology allows you to finely control the tilt angles and maintain perfect balance, even at low speeds. Adjust stability on the fly for maximum performance in tight turns or during intense acceleration.
- Customizable riding modes: Three modes are available:
- Street Mode: Ideal for hard surfaces, this mode limits wheelies to maximize acceleration.
- Dirt Mode: Perfect for rougher terrain, it adjusts power to handle jumps and obstacles.
- Wheelie Control: Unleash all the power to perform impressive wheelies and keep the front wheel up to maximum speed.

Robust and innovative mechanics
- Progressive rear suspension: Inspired by full-size motorcycles, this suspension adapts to your needs: flexible at low amplitudes for a smooth ride, and stiffer during impacts or jumps to avoid shocks.
- Adjustable front fork: With an internal spring system and hydraulic shock absorber, the front fork can be adjusted to change the riding height or the intensity of the shock absorption. Anodized aluminum tubes add an aesthetic touch and increase durability.
- High-performance braking system:
- Cable-operated front disc brake: This system uses a steel rotor and servo-operated pads, reducing braking distance by half.
- Rear engine brake: Complementing the front brake, it provides total control over the bike when descending or slowing down suddenly.
- Robust chain drive: The metal chain system, consisting of 70 pins and a steel Gear, ensures smooth power transmission and increased durability on all types of terrain.

A design focused on comfort and performance
- Slim aluminum chassis: The electronics and battery are ingeniously integrated into a compact and sturdy chassis, offering a realistic appearance and optimal weight distribution. In addition, the battery compartment allows the use of standard 2S LiPo batteries, which are easy to replace.
- Stands included: Two practical stands are provided:
- A maintenance stand for easy assembly and maintenance.
- A hands-free launch stand for quick and stable takeoff.
- Smooth steering damper: A chamber filled with ultra-viscous silicone oil (500,000 cSt) controls servo movement and limits vibration for stable steering, even at high speeds.

Power and speed for thrills
- brushless 4-pole 3652 3800Kv motor: This powerful motor delivers blazing acceleration and a top speed of over 40 mph.
- Spektrum Firma 85A intelligent ESC: This electronic controller manages power efficiently while protecting electrical components. It is compatible with Spektrum Smart technology for real-time feedback on battery, temperature, and more.
- Racing-inspired slipper clutch: This dual-disc clutch optimizes traction and protects the drivetrain without compromising explosive power.

Maximum durability and protection
- Reinforced plastics with durable graphics: The carFenders, mudguards, and side panels are designed to withstand impacts while maintaining a flawless appearance.
- Front crash structure: The front structure absorbs impacts to protect the fork tubes from deformation.
- Articulated rear fender: Designed to prevent damage during wheelies, this fender folds back to absorb shocks.
