Features

Legendary Performance

  • PRO-RIDE CHASSIS: The INDY 121 is built on the PRO-RIDE® chassis that is 300% stiffer for precise, intuitive handling. The ideal choice for a nimble handling sled that is fun to ride.
  • RACE-PROVEN FRONT SUSPENSION: Lighter steering, sharper cornering. Developed with the Polaris Racing Program, the performance and durability of the INDY 121 front suspension were proven in extensive on- and off-track testing.
  • INDY COUPLED REAR SUSPENSION: Legendary performance from the ride and handling experts. This proven design provides great ride quality in a conventional coupled design.

Proven Value

  • 550 FAN ENGINE: The proven, durable, fan-cooled 550 snowmobile engine provides reliable performance at a great value.
  • CVTECH POWERBLOCK50 / INVANCE CLUTCHING: All INDY models that feature the 550 Fan Engine use the CVTech PowerBloc50 drive clutch parried 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.

Simply Fun

  • LIGHTER WEIGHT: The INDY 121 is 50 pounds lighter with the PRO-RIDE chassis.
  • INDY PRO-RIDE SEAT: A wider surface right where the rider sits 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: The INDY 121 is 50 pounds lighter with the PRO-RIDE chassis.
