PRODUCT OVERVIEW
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 tyres 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 tyres 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 centre 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!

Realistic Rider Figure

The rider figures of other RC motorcycles are made entyrely of foam, which quickly fails. Promoto riders have 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. With its updated gear, the Promoto-SM rider looks ready for aggressive on-road racing action!


Realistic Chain Drive

We could not call the Promoto-SM a true street racing bike if wasn't chain driven. Steel links and 70 roller pins wrap around a 10-tooth steel drive sprocket and a 36-tooth aluminium hub sprocket. Regardless of conditions, the chain drive will drive the rear tyre efficiently and reliably.


Updated Lean Bars

The Promoto-SM lean bar positioning has been updated so it can lean farther than its dirt bike counterpart. New rubber lean bar tires, mounted on bearings, reduce noise and offer better traction on hard surfaces. Adjustable stops are included for up and down travel, so you can dial in the bike for any surface or grip level. The lean bars 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.


Updated Brake Calipers & Pistons

Although the original Promoto-MX front brake system worked well, the design team thought that improvements could be made. An all-new caliper and floating piston were designed to apply a larger pressure area to the brake pad. Also, a new Metal Injection Molded (MIM) piston shaft is installed on the bearings for smoother operation and a better seal again dust and debris. All of this adds up to a shorter stopping distance and more consistent braking operation.


Pro-Line Racing Supermoto Street Tyres

The Promoto-SM is outfitted with new Pro-Line Racing OE (Original Equipment) Supermoto street tires. In addition to complementing the bike's scale looks, the Supermoto tires are designed specifically for the unique wear and traction requirements of supermoto-style road racing.


Front Crash Structure

The front crash structure of the Promoto-SM is rigid during normal running, but compresses until the front tyre bottoms into the chassis frame to absorb front impacts. That protects the front fork tubes from bending, keeping them safe and true.


Skid Plates & Air Vents

Moulded composite skid plates line the front and bottom of the Promoto-SM chassis. They offer protection during crashes and keep debris 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.


Rear Fender

Wheelies happen. A normal, rigid-mounted rear fender would really take a beating. But the Promoto-SM 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.


Head Angle

After months of testing different trail settings, head angle, and steering ratios, the Promoto-SM product development team found the sweet spot. A head tube angle of 62.4 degrees gives it the best balance of bump handling, landing jumps, steering input, and "head shake" control on all surfaces.


Display / Maintenance & Starting Stand

Working on a real bike is easier with a proper bike stand. So the Promoto-SM 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-SM keys into the bike stand. But taking it a step further, a hands-free starting stand is also included. This starting stand cradles the rear tyre and holds the bike upright and ready for a gate-style start.


Technology

Losi product developers teamed up with the engineers at Spektrum RC, innovators of AS3X and SAFE, to reinvent those stabilization technologies not only for a surface vehicle, but one with only two wheels that requires balance to work. Patent-pending Spektrum MS6X continuously calculates bike's positioning relative to gravity, takes into account the inputs from the transmitter, and gives the proper outputs to throttle and steering to push the bike towards the correct desired positioning. The mechanical technology is just as impressive. For example, stopping distance was cut in half by joining the traditional rear-wheel brake with a cable-driven front braking system. The new technology all works behind the scenes to give the Promoto-MX performance superior to any previous RC motorcycle.


Spektrum MS6X Technology

The upgraded Spektrum DX3PM transmitter and SR6300PM receiver combine with patent-pending MS6X technology for unprecedented control. Promoto-MX drivers can maintain balance at high or low speeds and over jumps and whoops, then give simple steering inputs to carve around tight berms and straighten up heading into the next rhythm section. For more aggressive driving, use the MS6X knob to increase the lean angle


"On the Fly" Drive Modes

The DX3PM has three preprogrammed drive modes that you can toggle between "on the fly" using your thumb on the A/B rocker switch. Dirt Mode-For going up jump faces, Street Mode-To keep the front tire on the ground and Wheel Control-Let em' rip! Let's you hold wheelies all the way to top speed!


Smart Technology

How much battery life is left on your bike? You don't have to guess. LED indicators on the DX3PM transmitter show you the capacity of your Spektrum Smart batteries at glance! Using Smart Technology, the Promoto stores and shares critical performance data while you run.
