Losi Promoto RC Motorcycle Features

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.

Realistic Chain Drive

We could not call the Promoto a true street racing bike or dirt bike if it 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.

Twin Aluminum Plate Chassis

Twin aluminum chassis plates house and protect all of the bike's electronics and help to give the Promoto its realistically narrow appearance. They also give the frame the rigidity and durability required for harsh impacts.

"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!

Front Crash Structure

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.

Rear Fender

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

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 OE (Original Equipment) Supermoto Street Tires

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.

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.

Front Cable-Driven Disk Brake

Hauling on your bike is a lot more fun when you've got good brakes. The motor can handle rear braking through the drivetrain, but like 1:1 motorcycles, most of the braking happens with the front tire. To slow the Promoto-MX down from the front, the front brake uses a steel rotor, caliper-actuated brake pads, and servo-driven cable. It cuts your stopping distance in half — just what you need to catch the next berm.

Officially Licensed Dunlop Geomax MX53 Tires

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.
