Bad Boy enters ATV market with Onslaught 550

Liquid-cooled 503cc engine, other features bring $6,299 MSRP 

Bad Boy has entered the ATV market with the Onslaught 550 4x4, a mid-size four-wheeler designed to dominate a challenging trail or attack a long day of hard work.

The new Onslaught ATV features independent double A-arm front and rear suspension to enhance rider comfort as well as handling and maneuverability. An industry-leading 12 inches of ground clearance allows the Onslaught to move over terrain freely and easily.

A liquid-cooled 503cc engine with electronic fuel injection (EFI) delivers all the 4x4 power needed for challenging off-road rides or chores. Electronic power steering (EPS) is available to further ease the vehicle’s handling.

Two models are offered: Onslaught 550 4x4 EFI and the Onslaught 550 4x4 EFI EPS with electronic power steering. Both models are available in black or olive green, with Realtree Xtra camouflage and premium wheels offered as factory-installed options on EPS-equipped vehicles.

“We introduced the Onslaught in response to market demand for an ATV in the Bad Boy line,” said John Collins, vice president, consumer for Textron Specialized Vehicles, which markets Bad Boy off-road vehicles. “Onslaught offers comfort, control, power and styling for riders who simply want to do more in the outdoors. Whether it’s recreation or work, you can just bring it on and get after it with Onslaught.”

Bad Boy has released the Onslaught 550 4x4, with a 503cc liquid-cooled engine that brings a retail price of $6,299.
