VERSATILITY FOR WORK OR PLAY

With an ideal blend of work and play features, the TITAN Adventure is built to help you get the most out of winter

  • Get the Most Out of Your Day

The TITAN is built with a single focus… do-it-all. From work to play there is no more capable widetrack on the snow.

  • Increased Wind Protection

Widetrack riders know, the conditions aren't going to dictate where or when you ride. Add a tall windshield and passenger handguards for increased comfort on cold days.

  • Share the Fun

Featuring an easy to install, Lock & Ride 2-Up seat with integrated hand warmers and RCA outlet for added comfort, the TITAN allows you ride solo or share the adventure.

  • Bring It All

This sled features a standard tow hitch, integrated rack that supports up to 85 pounds, and storage box to help you get more done, more efficiently. Plus, Polaris-Engineered accessories allowing you to outfit your TITAN for whatever the day calls for.

CONFIDENT HANDLING FOR EVERY WINTER TASK

The TITAN is built to take you on-trail or off-trail with confidence and agility.

  • A Hard-Working Suspension

The Articulated Rear Suspension delivers a smooth ride on trail and absorbs bumps off-trail. With geometry for confident towing, and the rear of the skid tips up for easy backing up over obstacles. Plus, no adjustments are required when switching between solo or 2-up riding or when towing a large load.

  • Tailor Your Ride With a Quick Switch.

High-performance, adjustable, and rebuildable FOX® QS3 Clicker shocks offer easy adjustability and deliver outstanding performance on- and off-trail. The remote reservoir promotes heat dissipation and ensures consistently outstanding performance in all riding conditions.

  • The Right Ski For Your Needs

The TITAN is equipped with the industry-standard Gripper ski with the ideal blend of flotation and trail performance.
