We are very proud to announce that the long waited TrailMaster Challenger4 300E 4-seater UTV has arrived and with Electronic Fuel Injection!

The Challenger4 300E, now EFI with an 18HP powerful fully automatic engine, is a full size UTV that fits up to 4 adults. With a different gear ratio set up than our carbureted version, the EFI Challenger4 300E offers a lot more low end torque that will surprise you by the take-off power! This 4-wheel independent suspension beast goes over any tough terrain with ease. Like our other Challenger series side by side, it comes with nice looking graphics, digital speedometer/odometer, horn, adjustable steering wheel, 12v outlet, turn signals, bikini sunshade top, trailer hitch, front and rear disc brakes and etc.

Like our other Challenger models, the Challenger4 300E has optional winch, windshield, front steel bumper, top led light bar, and side view mirrors.
