A real gas ATV, not a ride-on toy

A 119.6cc 4-stroke gas engine, front dual A-arm suspension, a rear disc brake and 19" front / 18" rear tubeless tires. Built like a full-size ATV, sized for 125cc riders. LED headlights and a rear rack come standard, so it looks, sounds and rides like the real thing.

No clutch, no shifting

The 119.6cc 4-stroke engine runs an automatic transmission with reverse and electric start. New riders only need the throttle and the brakes. Press a button to start it, and if they get stuck against a fence, they shift into reverse and back out instead of climbing off.

Compact size, rated to 200 lb

A 27.5" seat height on a 59.8" × 37" frame, rated for one rider up to 200 lb. Small enough for backyard loops and narrow farm trails, with 3.54" of ground clearance for grass and dirt.

Thunder 125 FAQ

How big a rider does it fit?

X-PRO 125cc ATVs are rated for one rider up to 200 lb (about 90 kg). They are compact ATVs. Riders close to 6 ft tall or near 200 lb will be more comfortable on one of our 200cc ATVs.

What terrain can it handle?

Dirt trails, grass, gravel and backyard tracks. With a 125cc engine, it is not built for steep hills, deep sand or deep mud.

How is it shipped and how long does it take?

Shipping is free. We ship within 2 business days after your order is confirmed. Transit by freight truck is usually 4–7 business days. Addresses farther from Texas can take a few more days.

Will it be delivered to my door?

Delivery is curbside. The driver unloads the crate at the curb or the end of your driveway and does not carry it inside. Crates weigh about 230–290 lb depending on the model, so have two people ready to move it.

Do you ship to California?

No. X-PRO 125cc ATVs are EPA certified but not CARB certified, so we cannot ship them to California.

How much assembly is needed?

It arrives about 80% assembled. You install the wheels, handlebar, racks or bumper, shocks and battery.

What do I need to do before the first ride?

1. Drain the shipping oil and refill with 0.8 L of 10W-40.
2. Connect the battery and charge it fully.
3. Fill up with 87 octane gasoline.
4. Set tire pressure to 10 psi front and rear.
5. Make sure all bolts are tight.
6. Break it in: no full throttle for the first 300 miles or 20 hours.

We bought this for recreational riding and have been pleased with it. The LED headlights are a nice feature, especially when we're finishing up before sunset. The automatic transmission is simple to use and reverse comes in handy more often than I expected.

The Size Worked Out Well

The ATV itself has been running well and my kid enjoys riding it, but I spent more time than expected getting everything ready before the first ride. I wanted to check the adjustments and make sure everything was properly tightened. Once that was done, it performed well, and customer support was friendly and responded quickly when I had a question.

More Capable Than Expected

I was mainly looking for something that could handle our dirt and grassy areas without being overly complicated. This one has been doing a good job. The 125cc engine gives it enough power for our use, and the larger front and rear tires make it feel steady over uneven ground.

Started it up, let my kid get familiar with the controls, and he was having fun within no time. I like the straightforward automatic setup and the fact that there is a front and rear rack for carrying a few things. Pretty happy with it so far.

Assembly took a little time, but everything lined up well and the ATV started without any trouble after the basic setup was completed. It has enough power for riding around.

The Size Worked Out Great

This quad is a good size for the rider we bought it for. The larger tires make it feel substantial on grass and dirt, and the steering feels predictable. We have only used it off road on our property, but so far everything has worked as expected.

Easy to Get Used To

The automatic transmission was a big reason we chose this ATV. After a little practice, my son got comfortable with the controls pretty quickly. The reverse gear is also useful when he gets himself turned around in the yard. Overall it has been a fun addition for weekend riding.

The automatic transmission is very easy to get used to, and the reverse gear is especially helpful when turning around in tighter areas. The larger tires feel planted on grass and packed dirt, and the brakes respond smoothly without feeling too sharp.

Love it! great care in from the factory to assemble everything is top notch. welding is very good I might add. I gave it 4 stars because I will buy again however top speed is only 25MAX b4 the Rev. limiter kicks in. also I highly recommend spending $60 and purchasing the softest front shock assemblies you can find. Completely changed the ride 100% better.

My son and I spent a few hours putting this product together, but given the price, it was definitely worth it. Although the instructions were minimal, we were able to use the manual and various YouTube videos to help us assemble it. One important thing to note is that it is essential to change the oil right away, as we noticed a lot of metal flakes in the oil that came with it. Once we changed the oil and added fresh gas, the product ran perfectly. In fact, our family used it for 2.5 hours with no issues at all. We are so satisfied with this purchase that we are considering buying another one!

This ATV is a great purchase for anyone who wants a reliable and high-quality vehicle. It was easy to assemble, and the LED headlights are a great feature that makes it perfect for riding in low light conditions. The automatic transmission with reverse is also a big plus. The big 19"/18" tires provide a smooth ride over rough terrain. I highly recommend this ATV to anyone in the market for a great all-terrain vehicle.
