Realistic RC Motorcycle Experience!

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.

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!!

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!

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.

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.

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.

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.
