The 600 Voyageur® 144 is for riders that want an agile, all-purpose sport-utility snowmobile. This sled's Rider-Balanced™ AXYS® Chassis and IGX 144 Rear Suspension provide superb handling off-trail and on-trail. Key Features AXYS® Chassis: The AXYS chassis for the 144 platform is light and strong, offering rider balanced characteristics critical for the 50/50 rider. The rider is moved into a balanced position on the sled so it rides flat through the corners. When the trail gets rough or the rider jumps off into the powder, rider balance enables the rider to move back and make the front end light to climb up on top of the snow or the moguls. IGX 144 Rear Suspension: A core element to the AXYS 144 platform is the Ideal Geometry X-Over 144 uncoupled rear suspension, which offers the ultimate blend of durability and strength. The IGX 144 rear suspension provides RMK-inspired off-trail agility and balance with a drastically improved on-trail ride. Pitch is controlled through geometry in this rear suspension. With 43% more front torque arm travel, this sled features reduced bottoming and less drag off-trail. An optimized, lighter, tipped rail beam design gives the sled a nimble feel. PowderTrac™ Hybrid Running Boards: The PowderTrac Hybrid running boards offer optimized design with 56% open space for maximum snow clean out while maintaining extreme strength. Designed specifically for the crossover rider, the boards are wider and flatter in the front for comfort while sitting and better positioning while standing up. The rear of the boards tapers back for better mobility and snow clearance when carving. 600 Cleanfire® Engine: This liquid-cooled Cleanfire® engine with semi-direct injection (SDI) deliver outstanding throttle response and instant acceleration. These powerful, efficient engines start easily and reliably and they calibrate automatically as the temperature and elevation change. These engines deliver impressive fuel economy in real-world riding situations, which, for Polaris riders, means aggressive, up-tempo riding, not low-rev lab conditions. Now in the AXYS® chassis, the 600 engine features lightweight integrated mounts, electronic oil pump and bypass thermostat. Electronic Oil Pump: Electronic oil pump eliminates power-robbing gear drive - and provides more precise, improved oil delivery for performance and durability as well as a 35% reduction in throttle effort. Requires no adjustments.
