Promoto-SM 1/4 Super Moto Motorcycle FXR White: RTR Basic

Powering off the line, speeding down straights, and leaning through curves and turns, a unique harmony develops between a bike and its rider. The two intuitively become one. Despite its power, the two-wheeler feels light and nimble as it reacts instantly to your cues as if it's simply an extension of you.
That's also how it feels to drive Losi Promoto RC bikes.
The Losi Promoto-MX was the first RC dirt bike to accurately reproduce the full experience and pure fun of riding a real motorcycle. Now, for on-road RC and motorcycle fans, Losi presents the Promoto-SM the most authentic supermoto experience ever offered in a radio-control bike.
The Promoto-SM is particularly well-suited for concrete, asphalt, blacktop, and other hard surfaces found at neighborhood streets, local parks, and parking lots. Key differences from the Promoto-MX include new Pro-Line Racing OE (Original Equipment) SM street tires on smaller wheels, a more powerful front brake caliper, and revised lean bar wheels. The Promoto-SM can lean farther than its dirt bike counterpart, and the lean bar tires decrease noise and offer better traction on hard surfaces.
The Losi Promoto-SM also looks like a true supermoto bike. Its distinctive visual details include hand guards, shortened front fender, and officially licensed FXR graphics and rider gear.
What the Promoto-SM shares with the breakthrough Promoto-MX is an innovative blend of mechanical and electronic technology that work together to provide a realistic experience that no other RC bike can touch. The 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. Patent-pending Spektrum MS6X technology takes your input from the Spektrum DX3PM transmitter and commands the Promoto-SM to lean, turn, and wheelie with unprecedented balance and finesse.
The mechanical technology is equally impressive. Losi's product development team studied full-size motorcycle suspension geometry to give Promoto RC bikes the same terrain handling characteristics. A rising rate rear suspension provides superior grip and prevents bottoming out in landings. Their completely new 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 adds impressive stopping power, cutting the stopping distance in half compared to rear brake only.
Both technologies, electronic and mechanical, are why the Promoto platform performs better at high and low speeds than any previous RC motorcycle. Now, with the Losi Promoto-SM, there's an RC bike that really works with tarmac-ready performance and style!
