TM Challenger 300X 300cc Kids UTV Utility Vehicle Side x Side Razor

Our fully loaded Challenger 300X UTV has more major improvements!  

We upgraded our Challenger 300X to independent rear suspension! With the new improvement, users can drive a lot more aggressive! We redesigned the front end and rear end, which makes it a lot less vibration and much better turning and handling! 

Like our Challenger 150X, the top LED lights changed to the nice aggressive looking LED light bar! (See additional photos)

The TrailMaster name has become synonymous with high-quality, off-road vehicles, and their latest SidexSide keeps that banner flying! Dubbed the Challenger 300, this UTV extends the Challenger model into the 300cc category. The Challenger 300 has all the same awesome features found on other Challenger models, including big, polished aluminum wheels, dual sport bucket seats, full lighting, mirrors, a windshield, utility rack, trailer hitch and more! Power comes from a 300cc, water-cooled engine mated to a fully automatic transmission for simple operation. Adjustable rack-and-pinion steering and an adjustable drivers seat make it comfortable, too. The Challenger 300 is more than capable on the trails thanks to adjustable heavy duty front and rear shock absorbers and a 4-point rear swing arm setup. Safety comes from four-point seat harnesses, side nets and front and rear bumpers. The 300 comes standard with a ton of additional features, too, like a bikini sunshade top to keep all day riding cool and sunburn free, a big rear utility rack for hauling gear, and a handy trailer hitch that makes it perfect for towing a small utility trailer to hunting camp or using it to move trailers around on the farm! The bottom line is this is one of the best, all-around utility vehicles on the market today! CARB Approved. Comes in several colors.

This vehicle is also available in a CARB approved model that meets or exceeds guidelines established by the California Air Resources Board and can be sold in the state of California. CARB approved vehicles have modified engines and exhaust systems designed to reduce emissions.
CARB Approved Available! Just look for the 'CARB Approved' option when adding this item to your cart.
