About the RTR Promoto-MX
Suspension and Brakes
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.
Electronics
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.
Braaped Up!
Both technologies, electronic and mechanical, are why the Promoto-MX performs better at high and low speeds than any previous R/C motorcycle. For dirt bike fans, the “feel” of the Promoto-MX will be instantly familiar. R/C 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.

Anthony McBain Saturday, Jul 15 2023 (about 2 years ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Unexpectedly amazing. Always wanted a motorcycle but they seemed like a hassle. This changed the game completely! I hope they make an on-road bike eventually as well!! 7 customers found this review helpful. Johnny Ohearon Verified Owner Wednesday, May 29 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Took it out one time and accidentally flipped it about 4-5 times hitting a crack in the asphalt! After that the flywheel started making a screech and I can’t seem to get any help with it other than Jeff b from Amain hobbies! He’s been very helpful and is looking to get me a some parts for the flywheel to see if that works! The bike still runs and seems fine but if the flywheel is damaged after flipping like that even though it’s suppose to then idk what could’ve gone wrong! Love the bike but disappointed it’s already making a screeching sound after doing what it’s suppose to do when wrecking, flip! 2 customers found this review helpful. Martin Lung Verified Owner Wednesday, Feb 14 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Straight out of the box the front wheel won’t spin freely. Quality control seems to be lacking for a 500+ unit. I would not recommend buying this unless you are ready to take the bike apart before you even drive it. Buyer beware. 2 customers found this review helpful. Yaniv Oz Verified Owner Thursday, Feb 8 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Amazing rc motorcycle.
Amainhobbies service is excellent 🙂 2 customers found this review helpful. Derrick Grady Verified Owner Friday, Dec 15 2023 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) This is the most wonderful dirtbike I ever own. Right out the box. This thing is plenty of fun and may I say very fast at 50% is all I can handle at this moment.:)
May take me two more batteries in about 3 to 4 months to bump it up to 100%. So yes, it’s worth getting if you looking for it or wondering about purchasing. 2 customers found this review helpful. David Swartz Verified Owner Friday, Aug 2 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) I wanted to pop in and say Thank you to Jeff at customer service and also to Jose….you tried I received my Losi Promoto MX today and have had a issue with it but the Guys at A-Main are the Best and I am always looking forward to doing a large part of my R/C shopping here because of the price and availability…Thanks A-Main Bigtime Update. I love this thing. WOW first off it’s huge and next it is very fast for 2s . I might have found a new top shelfer.

Christopher Stanton Verified Owner Thursday, Feb 29 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Finally! An RC motorcycle that isn’t impossible to drive! Losi knocked it out of the park in this one. Don’t get me wrong, it definitely takes a bit of practice but nowhere near other motorcycles. So much fun. 1 customer found this review helpful. Curt Verified Owner Wednesday, Feb 14 2024 (about a year ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) This Dirt bike was a first for me, I’m very happy with it. Super fun, and fairly durable. It’s pretty awesome how many other manufacturers have made upgrades for it in the little amount of time it’s been out. If you are looking for something different, I would recommend it. 1 customer found this review helpful. Frank Henderpenson Verified Owner Monday, Aug 25 2025 (5 weeks ago) Losi Promoto-MX RTR 1/4 Brushless Dirt Bike (ClubMX) Its cool. The battery tray and rear fender have dependability issues and is a pain to constantly fix and then you have to spend over 60 dollars and hours to fix it since you can’t purchase the rear fender only. money making things like this is what gets people out of the hobby.
