DOWNLOAD FLYERHit the trail in the new Challenger 300EX (EFI) Side x Side UTV! The Challenger 300EX is an upgrade of the 300X with new (EFI) Electronic Fuel Injection. It even has an adjustable steering column and reverse! Plus, there's a full upper brush guard complete with sunshade canopy for all day riding, side protection rails with heavy-duty nylon safety nets and dual seats with seat harnesses to help keep you safe while riding.

The Challenger is powered by a reliable, Electronic Fuel Injected electric start 4-stroke engine, automatic CVT transmission and chain driven dual rear wheel drive. Stopping is extra firm thanks to 4-wheel hydraulic assist disc brakes, and the full suspension system and all-terrain tires help the Challenger crawl over the toughest trails. CARB Approved. The Challenger Side by Side comes in several great colors! Like our other Challenger deluxe models, the 300EX comes with aluminum wheels, windshield, side mirrors, front steel bumper and LED light bar.
