Rider Balanced Control

By placing the rider in the right location on the sled, we've built a sled that corners flat without sacrificing the fun factor of lifting the front end through the bumps or powder. More precise handling both on- and off-trail.


n AXYS Platform

The AXYS platform design is the key to delivering rider balanced control through the right rider positioning and centralized vehicle mass. The rider's hand position is moved 4.5" forward, the feet position is 2" forward, the knee position is 4.5" forward, and the seat is 4.5" forward. This means more bite for flatter cornering when in the neutral riding position and a lighter front end for climbing on top of the snow or the moguls when the rider shifts to the back of the sled.

 

n IGX 144 Rear Suspension

The IGX 144 rear suspension offers the ultimate blend of durability and strength. Pitch is controlled through geometry and with 43% more front torque arm travel, this sled features reduced bottoming and less drag off-trail. An optimized, lighter, reinforced tipped rail beam design gives the sled a nimble feel.
 

nPowderTrac® Running Boards

The PowderTrac® Running Boards offer an optimized design with 56% open space for maximum snow clean out while maintaining extreme strength. Perfect for on- and off-trail riding.


Unrivaled Acceleration
When developing the AXYS platform, our engineers minimized weight throughout the sled without compromising strength. Combined with powerful engines and class-leading power-to-weight ratios, the Switchback PRO S gives you the best go-anywhere versatility.

Rider-Centric Comfort
The world's best mountain sled is built to be the lightest and most rigid, making it incredibly responsive to rider inputs. This allows you to change direction and maneuver confidently in all conditions.

m
AXYS Performance Seat
The high-performance seat foam and narrow front design of the AXYS Performance seat delivers greater maneuverability. It's lighter without compromising comfort, offers improved ergonomics and stability, and its gripper top material helps keep the rider in place.

LED Lights
All AXYS models feature standard LED headlights for the industry's best lighting that last the entire lifetime of the sled. Nearly 1 lb. lighter with high beams 80% brighter than incandescent lighting. Low beams remain on at all times for constant visibility and enhanced safety.
m
Wind Protection
The hood and windshield design produce significantly enhanced wind protection for a rider, and the foil on the side panels further enhances protection.
m
Integrated Storage
Storage was developed with the AXYS platform, so it installs securely without tools and features seamless, integrated styling that matches the sled's design lines. Sturdier zippers provide better cargo security and protection.

Pro-Steer Skis

PRO-STEER skis feature a reshaped keep and shortened skag for reduced steering effort. Redesigned ribs atop the ski increase stiffness for more precise steering plus bosses added atop the ribs provide traction to prevent slipping when a rider steps on the ski in deep snow.
m
WER® Needle Shocks
Premium shocks with compression adjusters and remote reservoirs offer the best in tunability and fade-proof performance. Unique needle design uses hydraulic force at the end of the stroke to eliminate harsh bottoming.
m
