Description:

The Losi® Promoto-MX is not just another scale RC motorcycle — it’s the first RC bike that truly delivers the sensation, control, and excitement of riding a real dirt bike. Designed to fulfill the long-standing dream of RC enthusiasts and motocross fans alike, the Promoto-MX sets a new benchmark in realism and performance.

Its authenticity goes far beyond appearance. While the narrow frame, rider figure, and officially licensed graphics are impressively detailed, the real breakthrough lies in how accurately the Promoto-MX replicates true dirt bike dynamics. This is achieved through a groundbreaking combination of mechanical engineering and advanced electronic technology developed exclusively for this platform.

At the core of the Promoto-MX is a centrally mounted brushless motor paired with a high-RPM steel flywheel. Spinning at over 22,000 RPM, the flywheel generates gyroscopic stability that allows the bike to remain balanced at both low and high speeds. Spektrum’s patent-pending MS6X technology interprets your steering and throttle inputs from the DX3PM transmitter, enabling smooth leaning, precise turning, and controlled wheelies with unmatched realism.

Mechanically, the Promoto-MX mirrors full-scale motocross suspension design. A rising-rate rear suspension enhances traction while preventing harsh bottoming on landings. Up front, an all-new fork system with internal spring and damper allows ride-height adjustments and tuning via silicone oil changes. Braking performance is equally authentic, featuring functional front and rear brakes that significantly shorten stopping distances compared to rear-brake-only systems.

Together, these mechanical and electronic innovations allow the Promoto-MX to outperform any RC motorcycle before it — delivering confidence, control, and realism at any speed. Whether you’re carving berms, clearing jumps, holding wheelies, or throwing roost, the Promoto-MX delivers an immersive riding experience that feels instantly familiar to dirt bike riders and entirely new to RC drivers.

This is more than an RC bike — it’s a riding experience. Grab your Promoto-MX, choose your line, commit, and become the bike.

    True to size & Use a Drill
    Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
    Love this! Works perfectly for where I wanted it. I did measure my room incorrectly and thought it would be smaller, thankfully it’s not and thankfully it’s not bigger than the room itself. I did like how the whole thing was move-able but it was a bit annoying so I just added extra clips to the left of the middle one and unscrewed the right of the middle at the bottom so it opens like a door, this did make it a bit flimsy but duck taping it to the wall as anchor it works. 100% recommend, but do suggest a drill and a second set of hands to put it together, due to its size it can be a bit difficult to maneuver putting together yourself. Also if you have a clingy cat like I do, and think this will help keep them out, no, my cat who is very large can manage to squeeze underneath it.

    waste of money
    Color: Black, Size: 4 Panel-136‘’W-Round Pad
    This is a total waste of money. Its only going to free stand if you arent moving it. If you are planning on dividing a room, and then folding these for space and then dividing the room again, itll last a few days. The poles kept coming off of the screws that holds the fabric on the poles together. Was fixing this EVERY DAY. Finally got tired of doing this and just threw it out. Lot of money spent on garbage. Get a sheet room divider, or something that isnt cheaply made. Was simply making an office type space in a bedroom, to seperate the two areas for work, and folding it kept making the poles come off those twisted screws. just not worth it.

    Absolutely love this room divider!
    Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
    When they say you can't see anything through it, they are correct. As you can see by the video, the cars are traveling by with the sunlight on the divider and you still can't see any cars passing nor can you see the ones in the parking lot. You can also tell it blocks out the sunlight too which is a definite plus for our store. Quality material on the divider. Material is nice and snug on the poles with no ripples. I also like the base of these, they make the divider nice and sturdy and can be adjusted if floor is uneven. Also the design of the legs allow them to go under your furniture. Also putting them together is pretty easy. Just make sure you when you are putting the poles together to make sure at the top of the pole that the indent screw hole faces out. This makes for a better look. The directions don't say which way to turn and at 1st, I had one, one way and the other was another way as both ways work that way but I wanted a uniform/better look.

    Works well, need power tool to assemble
    Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
    Sturdy enough, especially when feet are positioned for balance. Works perfectly to create a WFH “cubicle”. Can adjust the size to provide complete privacy or fold back a panel when I want more openness. The fabric panels are not perfectly taught, but pretty close. The only negative is that without my husband’s power drill/screwdriver we wouldn’t have been able to put it together. It would take the strength of Thor to do it with just a manual screwdriver.

    Now I don't have to see the "black hole" that used to be my family room!
    Color: Black, Size: 4 Panel-136‘’W-Round Pad
    I have an adult child living at home and his bedroom is tiny, so he's pretty much taken over the family room. We are both much happier now that the divider is up. It is about 12 feet long and gives him privacy to watch his movies and play his video games. And I don't have to see all the shoot-em-up stuff he likes to watch. I put the divider together with just a screwdriver (not a power one, that would be nice but I don't have so I had to use a little elbow grease.) It took a couple hours. The instructions are straightforward. I did have to use my long dining room table to attach the feet to the divider panels, which was a bit tricky. But I'm really pleased with the end result. I'm NOT a handywoman, so I feel proud that I did it "all by myself." He wanted the black fabric, but I think the lighter colors would have been better for a room that gets hot in the summer. Just my opinion. Whatever color you choose, I think you'll like the end result.
