Overview

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.
