The Losi Promoto-MX isn't the first scale RC motorcycle that's ever been sold. But it is the very first one that accurately reproduces the full experience — and pure fun — of riding a real motorcycle. It's the long-awaited dream of RC hobbyists and dirt bike fans alike.
The unprecedented realism of the Promoto-MX goes much deeper than its faithfully detailed looks — the narrow frame, rider gear, and officially licensed graphics. Even more impressive is how successfully it captures true dirt bike performance, a breakthrough accomplished through a unique hybrid of mechanical and electronic technology developed specifically for the Promoto-MX. It's how these technologies work together that makes all the difference.
Promoto-MX electronics include a 2700Kv motor and steel flywheel that are both mounted in the center of the frame. The motor spins the flywheel at over 22,000 rpm to create a gyroscopic force for unparalleled stability. Meanwhile, patent-pending Spektrum MS6X technology takes your input from the DX3PM transmitter and commands the Promoto-MX to lean, turn, and control wheelies with unprecedented balance and finesse.
The mechanical technology is equally impressive. Losi's product development team studied full-size motorcycle suspension geometry to give the Promoto-MX the same terrain handling characteristics. A rising rate rear suspension provides superior grip and prevents bottoming out in landings. The completely innovative front fork design, with an internal spring and dampener, can be tuned by changing the silicone dampening fluid and also allows ride height adjustments. An innovative front and rear wheel braking system gives the bike impressive stopping power, cutting the stopping distance in half compared to rear brake only.
Both technologies, electronic and mechanical, are why the Promoto-MX performs better at high and low speeds than any previous RC motorcycle. For dirt bike fans, the "feel" of the Promoto-MX will be instantly familiar. RC car enthusiasts will discover a new way to drive that pulls you deep into the heart of the action — carving berms, skimming whoops, holding wheelies, and throwing roost.
Finally. An RC dirt bike that really works! Anytime and anywhere, just grab your Losi Promoto-MX, get in the zone, commit to your line, and begin to be the bike.

FLYWHEEL UNIT
The gyroscopic stabilization force created by its heavy steel flywheel — spinning at over 22,000 rpm with the 2700Kv motor — does wonders for the motorcycle's stability. Mounted as low and as far forward as possible in the frame, the flywheel unit enables the Promoto-MX to pivot around its center point to improve jumping, changes of direction, and the accuracy of the bike's performance.
LEAN BARS
Don't worry if the front tire washes out on loose dirt. The lean bars are ready to catch it. They'll keep the Promoto-MX from going over its maximum lean angle, helping push it back upright to straighten out and exit the turn. The lean bars have adjustable stops for up and down travel, so you can dial in the bike for any surface or grip level. They also often help with crash recovery when the rear tire has traction. If the bike is down on the track, simply hit the throttle to stand it upright and resume driving.
SERVO SAVER
The servo saver's stiff circular springs, captured by bearing-mounted composite plates, provide consistency in steering with enough give to protect the servo. But that's not all. It also drastically improves the bike's performance when setting down from wheelies, landing from jumps, power sliding through a turn, and pushing the front tire over a rut. It gives so the bike stays up.
HEAD DAMPING
With 8-pounds rapidly powering down the track, it takes quite a stiff servo saver spring setup to properly guide the Promoto-MX into the next turn. Like anything heavily sprung, the best way to control the strong springs is to dampen the movement. A key development for the Promoto-MX is a fluid-filled friction chamber between the upper and lower head tube bearings. The chamber is filled with heavy 500,000cSt which dampens the servo saver well and helps to control any possible "head shake."
NARROW CHASSIS
To capture the proper scale looks, the bike's electronics and battery all had to fit within a compact, narrow chassis. Requiring a special "shorty" battery would have made the design task simple, but the Promoto-MX product development team wanted to use a more convenient, standard size battery. Mission accomplished! A full-size 2S hardcase LiPo fits within the rider's seat, easy to access for quick battery changes. Pop in a charged pack and you're back to roosting your competition in seconds.
REALISTIC RIDER FIGURE
Complete with boots, brain bucket, and riding gear, the rider figure is ready for all of the same dirt bike-style action as you — to jump, wheelie, carve berms, and throw roost. The rider figures of other RC motorcycles are made entirely of foam, which quickly fails. The Promoto-MX rider has a rubberized plastic exterior that can give and flex under impacts and flips. To keep the rider from bobbling around on the bike, the torso has a foam insert. It keeps the body firm during normal operation but still able to give under impact.
OFFICIALLY LICENSED DUNLOP GEOMAX MX53 TIRES with TRUE-SPOKE WHEELS
Just as any real dirt bike rider would want, the Promoto-MX comes equipped with the most popular Dunlop dirt bike tire tread, the Geomax MX53. It's officially licensed by Dunlop for scale accuracy and performance. The MX53 delivers on full-scale moto tracks around the world, and it provides high grip and long tire life for the Promoto-MX.
OFFICIALLY LICENSED FXR RACING GRAPHICS
Losi partnered with FXR Racing — a leading manufacturer of helmets, jerseys, pants, and other accessories for full-scale dirt bike enthusiasts — to create the officially licensed graphics for the Promoto-MX. The Promoto-MX looks perfect. It's ready and waiting for the gate to drop.
DISPLAY/MAINTENANCE & STARTING STANDS
Working on a real dirt bike is easier with a proper bike stand. So the Promoto-MX had to have one, too! The included stand for maintenance and display is modeled after a real bike stand, complete with graphics. To keep the bike balanced on the stand, the Promoto-MX keys into the bike stand. Taking it a step further, a hands-free starting stand is also included. This starting stand cradles the rear tire and holds the bike upright and ready for a gate-style start.
PLASTICS WITH GRAPHICS and REALISTIC DETAILS
Big or small, no dirt bike would look right without a proper body panel kit wrapped in vinyl graphics. The Promoto-MX has all the goods — front fender, number plate, fork guards, front side panel, rear side panel, and rear fender — all looking fresh wrapped in officially licensed vinyl graphics, but highly durable and ready to get dirty.
FRONT CRASH STRUCTURE
There's nothing better than sending a huge triple, but what happens if you come up short? Bending a fork leg or tube was not an option, so the Promoto-MX product development team found a solution. The front crash structure is rigid during normal running, but compresses until the front tire bottoms into the chassis frame to absorb those massive front impacts. That protects the front fork tubes from bending, keeping them safe and true.
REAR FENDER
Wheelies happen. A normal, rigid-mounted rear fender would really take a beating. But the Promoto-MX has the solution — a hinged elastomer sprung rear fender that can deflect out of the way during wheelies to expose a durable nylon rear bumper. It substantially increases the durability of the rear fender.
SKID PLATES & AIR VENTS
Molded composite skid plates line the front and bottom of the Promoto-MX chassis. They offer protection during crashes and keep roost out of the chassis, helping to protect the electronics mounted inside. The air vents on each side of the bike come closed in the box, but can be opened to provide cooling airflow when ambient temperatures are high.
RISING RATE REAR SUSPENSION
Just like a real dirt bike, the Promoto-MX has a rising rate rear suspension. The suspension starts soft around ride height, for smooth handling and a superior grip. It becomes firmer as it gets deeper into up travel, to provide proper preload on jumps and prevent bottoming out in landings. Dialed in with a full oil-filled coil-over shock, the Promoto-MX is ready to rip on any surface.
FRONT FORK
The front fork of the Promoto-MX is a completely new and modern design with an internal spring and dampener. Designed to work similar to normal RC shocks, the front fork tubes can be rebuilt and tuned by changing the silicone dampening fluid. Using counter-wound upper and lower springs, spacers can be used to adjust the ride height of the Promoto-MX as well. And maybe most importantly, they look awesome — just like the real deal.
RACE-INSPIRED SLIPPER CLUTCH
As its 3800Kv Firma Brushless motor puts out abundant power, the Promoto-MX's race inspired dual disc slipper clutch helps the Dunlop Geomax MX35 rear tire keep traction on loose surfaces. The dual pad, spring pressurized slipper clutch takes inspiration from those that the TLR team uses to win races across the globe. It increases traction and protects the drivetrain without sacrificing explosive drive.
