About this item

Product details

This ATV Four Wheeler is a popular recreational vehicle for kids. It boasts a 40cc 4-stroke engine that delivers impressive power while remaining fuel efficient and environmentally friendly. To ensure the safety of beginners, parents have the ability to adjust the maximum speed using a speed governor. Typically, the maximum speed is around 13 mph, depending on weight and terrain. The cooling system is Air Cooled, and the product net content UOM is "Each". With a convenient pull start feature, children can easily start the vehicle by simply pulling a cord. This ATV is the ideal choice for young riders who want a thrilling and safe off-road experience.

Key Features:
- 【Eye-catching Water Transfer Decals】The X-Pro Thunder 40 ATV doesn’t just ride wild—it looks untamed, thanks to its head-turning hydrographic camo and graphic designs!The water-transfer printing isn’t just for show—it’s ultra-durable, scratch-resistant, and gives the ATV a custom, ‘factory-hotrod’ vibe straight out of the box.
- 【Chain Transmission with Pull Start】Chain Transmission and Pull Start provides much easier control and handling and gives the rider the great convenience in the event of a stall. Front and Rear Disc Brake provides a better stopping power compared to regular brake.
- 【Safty Features】Safety meets performance on the X-Pro Thunder 40 ATV—where every ride stays under control, no matter how wild the adventure gets! Built with serious safeguards for young riders, this beast packs dual hydraulic disc brakes (front & rear) for ultra-responsive stopping power, so muddy trails or sudden stops never stand a chance. The parking brake locks solidly in place—no annoying rollaways on hills—while the emergency kill switch instantly cuts the engine with one tug.
- 【EPA approved with Safety Concern】

Though it has not been used yet, final assembly was simple and took about 90 minutes. I suggest use of regular tools if you have them vs supplied tools. Runs good, started easily and the grandson will love it. ps, not made for a heavy user, just a youngster...

I recently purchased this for my 5 year old daughter for Christmas. My husband put this together in about hour or less. I would say this is definitely a 5-9 year old starter. My 5 year old daughter loves it she went mudding after it rained lol. I would say it's good quality and reasonable price. Definitely would buy again.
