2014 Bennche Bighorn 400, 2014 Bennche Bighorn 400 Small size, big help! Don't want to haul a trailer, but need a UTV? The Bighorn 400 is small enough to carry in your truck bed and powerful enough to handle your lightweight work. A 392 c.c. liquid-cooled engine provides 21.7 HP for this small workhorse, which measures just 102" long x 52" wide. Like our other Bighorn models, the Bighorn 400 comes standard with a top cover, windshield, aluminum wheels, and winch. It also meets safety requirements for a low-speed vehicle so you can get a license plate and take it to the streets.
