Features

Legendary Performance

  • PRO-RIDE™ CHASSIS: The INDY® is built on the proven PRO-RIDE™ Chassis that is 300% stiffer for precise, intuitive handling. The ideal choice for a nimble handling sled that’s fun to ride.
  • RACE-PROVEN FRONT SUSPENSION: Lighter steering, sharper cornering. Developed in conjunction with the Polaris Racing program. Its performance and durability were proven in extensive on- and off-track testing.
  • COIL-OVER REAR SUSPENSION: Designed for better flotation and deep snow performance with improved on-trail ride. By eliminating the torsion springs and redesigning the torque arms, this skid weighs substantially less.

Proven Value

  • 550 FAN ENGINE: Proven, dependable two-stroke engine with NiCaSil-lined cylinders provides trail cruising power in a lightweight package.
  • CVTECH POWERBLOC 50/INVANCE CLUTCHING: All INDY® models powered by the Polaris 550 fan-cooled engine use the new CVTech Powerbloc 50 drive clutch paired with the Invance driven clutch. This clutching delivers smooth engagement, enhanced low-speed drivability and quieter operation. These durable clutches have a maintenance-free design and are easy to tune while installed on the sled.
  • ELECTRIC START: Start your sled with the turn of the key. Nothing beats the ease and convenience of electric start.

Simply Fun

  • LIGHTER WEIGHT: The 550 INDY® 144 is 50 lbs. lighter with the PRO-RIDE™ chassis.
  • INDY® PRO-RIDE™ SEAT: A wider surface right where a rider plants for seated riding provides enhanced comfort during long days on the snow, and the seat design allows easy transition between seated and standing positions.
  • HANDLEBAR AND STEERING POST ANGLE: INDY® 550 design - 15 degree flatter steering post angle developed for sitdown and standup riding comfort and flexibility.
