The TrailMaster Challenger 300EX EFI UTV is a fully loaded side-by-side designed for riders who want strong performance, comfort, and dependable capability on trails and rough terrain. Powered by a 276cc, 4-stroke, single-cylinder, water-cooled engine with Electronic Fuel Injection (EFI), the Challenger delivers up to 17.4 HP at 6,500 RPM and reaches a top speed of approximately 45 MPH. Its fully automatic CVT transmission with reverse makes operation simple, while the chain-driven dual-wheel drivetrain provides reliable power delivery for recreational and utility riding.

The Challenger 300EX features a 4-wheel independent suspension system with independent dual A-arm front suspension and independent swing-arm rear suspension. This upgraded IRS design helps improve handling, cornering, ride comfort, and stability over uneven terrain. Large 22-inch all-terrain tires, aluminum wheels, heavy-duty shocks, rack-and-pinion steering, and four-wheel hydraulic disc brakes give the UTV the equipment needed for challenging trails, hills, sand, and rough surfaces. The adjustable steering column and driver seat also allow the cabin to accommodate taller riders comfortably.

This deluxe Challenger comes equipped with a wide range of extras, including a front steel bumper, upper brush guard, windshield, LED light bar, side mirrors, bikini sunshade top, side safety nets, four-point seatbelts, individual sport seats, turn signals, horn, trailer hitch, 12V outlet, speedometer, and odometer. The large rear utility rack provides additional cargo space, while the 500-lb maximum load capacity adds practical utility.
