Built to Deliver Spirited Trail Performance.

Cruise the trail and visit new places. When the snow starts to fly and the winter playground opens up, INDY SP provides comfort and control to navigate the trail system.

Features may include:

  • Rider First Design. Effortless Control.

The INDY on the Matryx platform is a trail rider's dream. The narrow cockpit provides improved rider connection to the sled to help you move around the sled for trail precision.

  • Navigate the Trails. Smooth Cornering.

The PRO-CC is the next generation coupled rear suspension design, providing the industry's best acceleration, handling, and consistently smooth ride. The coupled design controls pitch through geometry without reducing the fun factor, with a front torque arm calibrated for trail compliance for reduced bottoming.

  • Smooth. Powerful. Fuel Efficient.

Choose between the long service intervals and fuel efficiency of the ProStar S4 4-stroke engine or the smooth and powerful 650 Patriot 2-stroke engine.
