ATV-3125R Fully Automatic Junior 120CC ATV
120CC Fully Automatic Junior Sized ATV
Available Colors
The Coolster 120cc ATV-3125R is a reliable junior 120cc ATV built for younger riders who are ready to step up from a smaller quad. This 120cc four wheeler comes equipped with a strong steel frame, a fully automatic transmission with reverse, and 16-inch wheels that provide solid ground clearance and stability on uneven terrain.
Key Features of the 120cc Quad
- 120cc engine with fully automatic transmission and reverse for easy operation
- Hydraulic rear disc brakes for confident stopping power
- 16-inch wheels for improved traction and a smoother ride over rough ground
- Heavy-duty front and rear racks for hauling gear on the trail
- Comfortable foot environment with wide, textured footrests
- Strong steel frame built to handle regular use across varied terrain
The ATV-3125R sits in the sweet spot for junior riders who’ve outgrown a 110cc but aren’t ready for a full mid-size machine. The automatic transmission lets them focus on riding instead of shifting, while reverse makes it easy to back out of tight spots on the trail. The front and rear racks add utility that most youth ATVs don’t offer, which makes this a great option for families who want a quad that works as hard as it plays.
