The Ultimate MX Experience: Promoto-MX Ready to Run

The Losi Promoto-MX Ready to Run 1/4 Brushless Dirt Bike will make you feel like you belong on an MX track doing what could only be described as getting after it, brapping it up, giving it the zip zip zip! When the gate drops this Bike's Brushless powerhouse will have you shooting for the holeshot, blitzing through the whoops, and airing it out over triples!

The mechanical technology is equally impressive. Losi's product development team studied full-size motorcycle suspension geometry to give the Promoto-MX the same terrain handling characteristics. A rising rate rear suspension provides superior grip and prevents bottoming out in landings. The 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 gives the bike impressive stopping power, cutting the stopping distance in half compared to rear brake only.

The 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.

Both technologies, electronic and mechanical, are why the Promoto-MX performs better at high and low speeds than any previous RC motorcycle. For dirt bike fans, the "feel" of the Promoto-MX will be instantly familiar. RC car enthusiasts will discover a new way to drive that pulls you deep into the heart of the action, carving berms, throwing fat whips, skimming whoops, casing jumps, holding wheelies, and throwing roost.

Wow! This is good. Very very good. Surprisingly easy to drive. The S120 charger takes forever, so maybe consider grabbing the S150 charger and an extra 5000mah battery because you're going to want to run this thing over and over again. Also, it's pretty big and requires a good amount of space to run.

The best rc motorcycle ever created. 100% worth the wait! I pre ordered from Amain because I know they will always have my back. You can actually talk to a human who enjoys talking about RCs. If you are still undecided about the promoto mx you're missing out on the greatest RC that has came out in over 10 years. I own every RC dirtbike and streetbike even the older Thunder Tiger Nitro Ducati. The promoto mx is on another level. Even my $2500 RC racing streetbike doesn't compare. Losi hit a homerun
Get yourself one, or three.

I never considered getting a RC bike because I always thought it was difficult to drive being that it’s only on two wheels but the Losi Promoto is so easy to control. Not only that but the scale realism of it makes it very enjoyable to watch as it’s being driven. Hope Losi will come out with a TLR tuned version of it. Regardless, Losi really did a great job on this bike.

Losi hit the ball out of the park with this one. I purchased one and my buddy picked one up the next day. Between the two of us we have roughly- well a ton of cars- this is the first that had us laughing and smiling like little kids again.

The ease of use is amazing. After a few minutes of getting used to the feel it was came on. The first roll and scuff on the jersey hurt for a split second then it was back to playing.

First time drivers, forget everything you know about driving cars. It does not apply- think back to learning how to ride a bike and how little changes impact the steering.

The brakes are very good, but they do not stop like a normal r/c car and be cautions with turning radius- the faster you go the wider the turn.

Have several packs ready. We tested many different brands and all the packs we had that were 2S fit as long as they were a standard size case. There is little room to hide balance wires so you have to be creative. My favorite was a powerhobby 8000 100c. I didn’t have any larger to test. Gave plenty of run time with no heat issues.

The smart battery and charger are a real nice feature- however with a usbc cord it will take several hours to charge from cut off.

I would have to give it an A++ and would highly suggest dropping the coin. Well worth it.

After waiting 4 months, I haven’t had many minutes to drive my new toy, to cold or raining. Had a friend last week walked into his local hobby shop and buy one off the shelf, glad for him but a little peeved that it took 4 months to get mine. I will still shop at you store, but I’m not sure it will be my go to store.
