    This is a GREAT trail bike! Has fantastic suspension front and back, engine is smooth with very tractable power, and bike is put together very well. It's no power-house, but it will move when you want it to. The engine is as reliable as they come, especially when proper maintenance schedules are followed. The exhaust note is really LOUD, but with a quiet core install it will bring the Db's down to acceptable levels. I am looking forward to many, many miles of fun and trails with this dirt bike.

    RXB-250 Exceeded Expectations

    Posted by Ken Allhands on 29th May 2019

    I was skeptical, as most are with a "blind purchase", but both the experience and the bike itself truly impressed me.

    With just minor adjustment of the suspension, I was enjoying myself more on this bike that I had on my last two dirt bikes put together. Actually, I'm faster on this bike than my old projects because I can confidently use all the bike has to offer.

    Quality is higher than I expected, ergonomics are good, and performance is just what I wanted...race-bike handling with an engine I can use all of.

    I'm looking forward to many years of riding this one.

    2019 Orion XB39

    Posted by Isaac on 19th May 2019

    I bought this bike with really low expectations but I must say it has surpassed them greatly. With this bike being so new, there really weren’t a lot of helpful videos or reviews online. Buying it pretty much blindfolded was a great buy though. This thing looks sick, sounds great and rides really nice. I’ve ridden it about 5 hours total now and haven’t had any issues or complaints yet. The power isn’t like an mx bike, but is super manageable and it’s there when you need it, the electric start makes the riding experience a breeze but having the kickstart as a backup is really nice too, tires grip well from the factory and put down a smooth ride. This bike is the perfect bike to have if you want a trail rider, a bike to ride with your kids, or just a spare bike to have in case you got a buddy that wants to tag along. As far as putting it together goes, it was pretty self explanatory. If you’re not mechanically inclined, I would recommend getting it assembled. If you’re eager to learn, get it unassembled and learn something! This bike is great for beginners, intermediate, or even long time riders. You can’t beat that price for a brand new bike either, I can’t imagine spending $8-$9k on something similar. I’m very impressed with this bike overall, and would definitely recommend it to anyone looking for a good bike at a great price. The staff at Orion Powersports were grade A professionals too, answering any questions or concerns I had and in a very short amount of time. I’ll be enjoying this bike for a while, and it definitely won’t be my last buy from Orion Powersports! (Next bike: Orion XS125)

    Orion RXB-250

    Posted by Jack Baltzly on 14th Apr 2019

    This bike looks like a motocrosser, but it's a trail bike. My son is riding an XR250, so that's my comparison. We rode together all day, and on trails, my RXB was equivalent. On hill climbs, the RXB had the power and torque to climb any hill, no matter how steep. The only time the XR outshone my RXB, was a very long, high speed uphill. The XR pulled away from the RXB, since it has 30hp compared to the RXB's 18hp.

    Most of my riding is in the woods on tight trails, riding with my younger kids on smaller trail bikes and quads. My RXB feels light and nimble in the woods, on trails that are tight, but nothing too technical like jumps or tree crossings.

    I'm loving my RXB.

    Also, it sounds great! And, my first off-road bike with electric start. Now wouldn't have it any other way.

    Bike arrived in a timely manor and was ready to roll as soon as it got off the truck. On week 2 of having the bike and I'm having 0 problems and love the bike. Highly recommend this bike if you want a great bike but don't want to shell out the extra money for the more expensive ones.

    Really nice bike

    Posted by Grayson on 3rd Feb 2019

    Just got my XB39 in and i have to say, i am utterly surprised at how nice this bike is. Lots of attention detail from the brake guards to the chain tensioners to the perfect offset position of the gas cap. Really impressed with the suspension as well. Adjustable rebound and compression on the forks and rear shock make it easy to dial in.
    Perfomance was eaqually as good. At 18HP i did not expect it to be a race bike but the torque on this bike reminds me of my old XR250 and the sound is very deep and throaty like you would expect out of a 4 stroke. All in all, very impressed. It started right up and runs like champ. Great job Orion!
