Coolster 3125F2 ATV FAQ
Check out our FAQs for answers about questions regarding our products, orders, shipping, return, and warranty policies.
What age rider is the Coolster 3125R best for?
The 3200U is a mid-sized 169cc sport quad designed for youth riders ages 12 and up. Its aggressive, aerodynamic frame and 725mm seat height provide a commanding and stable riding position, making it the perfect upgrade for growing riders who have outgrown smaller 110cc units.
How does the remote kill switch work?
The remote kill switch allows a supervising adult to turn off the engine from up to 65 unobstructed feet away with the touch of a button. It's the ultimate safety net for new riders.
Does this ATV have a reverse gear?
Yes! The 3125F2 is equipped with a fully automatic transmission that includes Forward, Neutral, and Reverse (R-N-F). This feature allows young riders to easily back out of tight spots on the trail without needing to manually push the vehicle.
What is the top speed of the Coolster 3125F2 and is it adjustable?
The Coolster 3125F2 reaches a restricted top speed of 15 mph, though actual performance will vary depending on the rider's weight and terrain. For added safety, the vehicle is equipped with a built-in adjustable speed limiter on the thumb throttle. This mechanical governor allows parents to restrict speed, ensuring the vehicle stays at a controlled pace suited for the rider's current skill level.
Is the Coolster 3125F2 delivered fully assembled or partially assembled?
We offer two convenient options for your vehicle's delivery:
You can choose Partially Assembled, where the unit arrives 85-90% complete in a protective box (requiring you to install the
handlebars, wheels, and battery).
Alternatively, you can select our Professional Full Assembly Service at checkout. With this option, our technicians fully assemble, test, and prep the vehicle so it is ready to ride the moment it arrives (just add fuel).
How long will it take to get my orders?
Orders typically arrive within 7-12 business days. All orders ship via specialized freight carriers to ensure your vehicle arrives safely. Once your unit ships, the freight provider will call you directly to schedule a delivery appointment.
