Celebrating their 50th anniversary, Arctic Cat pulled the cover off an all new snowmobile chassis. The new rider-forward ProCross chassis features a triangulated upper spar assembly and a tapered two-piece tunnel that reduces weight while adding strength. A new chain case replaces the Diamond Drive direct drive system, along with a new braking system. Arctic Race Suspension up front with tall A-arms improves handling and comfort. Twenty models feature the new ProCross chassis. Engine choices include the 1100, 1100 Turbo and 800 H.O. 2-stroke. Visit Arctic Cat for more details.
