Losi Promoto-MX 1/4 Motorcycle RTR Combo, Pro Circuit
Product Overview
The Losi Promoto-MX 1/4 Motorcycle RTR Combo, Pro Circuit is a highly detailed electric RC dirt bike designed to reproduce the appearance, balance, and riding characteristics of a full-size motocross motorcycle. The LOS06002 configuration features officially licensed Pro Circuit graphics and rider gear, a powerful brushless system, Spektrum MS6X stabilization technology, and a frame-integrated high-RPM flywheel.
Unlike a conventional RC car, the Promoto-MX is engineered around two-wheel dynamics. Its mechanical and electronic systems work together to help the motorcycle maintain balance, lean through turns, and respond naturally across dirt and other riding surfaces.
Best of all, this Ready-to-Run (RTR) Combo includes the battery and charger, so the main power components needed to get started are included in the box.
Key Features
- 1/4-scale RC dirt bike with realistic motorcycle proportions.
- Officially licensed Pro Circuit graphics and rider gear.
- Spektrum MS6X technology provides electronic stabilization and control assistance.
- Frame-integrated high-RPM flywheel generates gyroscopic force to improve stability.
- Brushless 540 motor delivers strong performance and speeds of 40+ mph.
- Dirt, Street, and Wheelie drive modes provide different riding characteristics.
- Dunlop Geomax MX53 tires feature officially licensed motocross tread.
- True-spoke wheels provide a realistic motorcycle appearance.
- Functional cable-driven front disc brake adds authentic braking operation.
- Rising-rate rear suspension helps maintain traction and control.
- Collapsible front crash structure helps protect the fork during impacts.
- Twin aluminum plate chassis provides rigidity and durability.
- Steel chain drive with slipper clutch reproduces the mechanical character of a dirt bike.
- Fully assembled RTR package includes the battery and charger.
Pro Circuit Edition
The LOS06002 is distinguished by its officially licensed Team Pro Circuit graphics and rider gear. Losi worked with Pro Circuit to reproduce the team's distinctive motocross appearance on the Promoto-MX, including the body graphics and rider presentation.
This makes the model appealing not only as a high-performance RC motorcycle but also as a detailed scale representation of a professional motocross machine.
Spektrum MS6X Stabilization
The Promoto-MX uses Spektrum MS6X technology, combined with the DX3PM transmitter and dedicated Promoto receiver. The system is designed specifically for the unusual balance requirements of a two-wheel RC motorcycle.
The transmitter also provides access to the model's different drive modes, allowing the rider to select settings suited to dirt riding, street-style operation, or extended wheelies.
Brushless Power System
A Spektrum Firma 3652 3800Kv 4-pole brushless motor powers the motorcycle through an 85A Spektrum Firma Smart motorcycle ESC. Losi rates the Promoto-MX for speeds of 40+ mph under the specified setup.
The included battery is a Spektrum Smart G2 2S 7.4V 5000mAh 50C LiPo with an IC5 connector. A Spektrum Smart S120 USB-C 20W charger is also included, making this version substantially more complete than Promoto-MX configurations that require a battery and charger to be purchased separately.
Realistic Motorcycle Design
Losi has incorporated numerous details intended to make the Promoto-MX resemble a real motocross bike:
- Narrow motorcycle-style chassis
- Realistic rider figure and gear
- True-spoke wheels
- Licensed Dunlop MX53 tires
- Steel chain drive
- Functional front disc brake
- Motorcycle-style suspension
- Front crash structure
- Pivoting rear fender
- Skid plates and air vents
- Twin aluminum plate chassis
The included keyed bike stand supports display and maintenance, while the hands-free starting stand holds the motorcycle upright for starting and gate-style launches.
Suspension & Braking
The Promoto-MX uses a front fork and rising-rate rear suspension. The rear system becomes progressively firmer as it compresses, helping the bike maintain control over changing terrain and during harder landings.
Braking is also designed with motorcycle realism in mind. The front uses a cable-driven piston, caliper, and rotor, while the rear receives braking through the motor.
