Features may include: The PRO-RIDE chassis is a proven platform. Strong and light. The Liberty 550 engine is fan-cooled to provide consistent power, regardless of snow conditions. The clutching is equipped for smooth engagement and enhanced low-speed drivability. The 144 Coil-Over Rear Suspension is designed for better flotation and deep snow performance with an improved on-trail ride. By eliminating the torsion springs and redesigning the torque arms, the skid weighs substantially less.
