The Challenger4 300X, now EFI (electronically fuel injected) with an 18 horsepower powerful fully-automatic engine, is a full-size, fully-featured UTV Side-by-Side that fits up to 4 adults! With a durable water-cooled 275.6cc engine, this SxS can cruise up to 35 miles per hour, and with over a half-foot of ground clearance you can take it on even the roughest terrain with no problem. TrailMaster has even added a new gear ratio set up to enhance low-end torque. So now you can get even more use out of the included trailer hitch with a max loading capacity of 700 pounds! The Challenger4 includes safety features such as an emergency engine kill switch, front and rear hydraulic disc brakes, and four-point safety seatbelts for all riders. Premium features in the X series include aluminum alloy wheels, an LED light bar and an improved windshield. This rugged side-by-side includes features that always come standard on the Challenger UTV series like a digital speedometer/odometer, horn, adjustable steering wheel, 12v outlet, turn signals and a bikini sunshade top. Comes in a selection of great colors with exciting graphics! EPA Certified.
