Description

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! SMART TECHNOLOGY In The Box Needed to Complete Fresh styling and key feature updates combine with proven Promoto mechanical and electronic technologies to make the Losi Promoto-SM an RC bike that excels on-road — bringing supermoto looks and performance to the tarmac. Losi 1/4 Promoto-SM FXR Supermoto RTR RC Motorcycle Features 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. The included Spektrum DX3PM transmitter and SR6300PM receiver combine with patent-pending MS6X technology for unprecedented control. Promoto-SM drivers can maintain balance at high or low speeds while maneuvering over concrete, asphalt, blacktop, and other hard surfaces. For more aggressive driving and extreme cornering angles, use the MS6X knob to increase the lean angle. The DX3PM has three preprogrammed drive modes that you can toggle between “on the fly” using your thumb on the A/B rocker switch. 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. 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-SM to pivot around its center point to improve jumping, changes of direction, and the accuracy of the bike's performance. With eight pounds rapidly powering down the track, it takes quite a stiff servo saver spring setup to properly guide the Promoto-SM 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 platform 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.” 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 curb. It gives so the bike stays up. 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-SM 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 in seconds to leading your competition. The rider figures of other RC motorcycles are made entirely 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! 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. 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 tire and holds the bike upright and ready for a gate-style start. Before Losi introduced the Promoto platform, no other manufacturers had been able to create proper-looking spoked wheels with the durability needed for an RC bike. It took the determination and expertise of the Losi product development team to make it happen. For the Promoto-SM, the realistic, true-spoke wheels are smaller, in keeping with the design of real on-road motorcycles. Big or small, no street bike would look right without a proper body panel kit wrapped in vinyl graphics. The Promoto-SM has all the goods — fenders, number plate, fork guards, front and rear side panels — all looking fresh wrapped in updated, highly durable vinyl graphics. Even tiny touches matter, and Losi hasn't overlooked a thing — exhaust, brake line, foot pegs, brake rotors, you name it. The Promoto-SM also includes hand guards, recreating those used on full-size supermoto bikes to protect the brake and clutch levers during a fall. 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. The front crash structure of the Promoto-SM is rigid during normal running, but compresses until the front tire bottoms into the chassis frame to absorb front impacts. That protects the front fork tubes from bending, keeping them safe and true. Molded 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. 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 aluminum hub sprocket. Regardless of conditions, the chain drive will drive the rear tire efficiently and reliably. The Promoto-SM comes out of the gates HOT with a powerful Spektrum Smart brushless power system. Its 4-pole 3652 3800Kv motor puts down the power while the 85A brushless ESC adds all the control you need. With massive 40+ mph top speeds on a 2S LiPo battery, the Promoto-SM power system rips! Just like a real bike, the Promoto-SM 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-SM is ready to rip over any on-road surface.
