The new Onslaught ATV features independent double A-arm front and rear suspension and an impressive 12 inches of ground clearance. Muscle comes from a 503cc single-cylinder engine with electronic fuel injection that produces a claimed 39 horsepower.


2008 Bad Boy Buggy Review Bad Boy is offering its new ATV in two configurations – Onslaught 550 4×4 EFI and the Onslaught 550 4×4 EFI EPS with electronic power steering (EPS).

Whether it’s recreation or work, you can just bring it on and get after it with Onslaught.”
