Confident Handling

  • MAXIMUM TRACTION: Featuring a massive 20" x 155" Cobra two-ply track, in either 1.5" or 1.8" lug height, the TITAN combines flotation and traction allowing you to explore more.
  • BUILT TO BREAK TRAIL: The TITAN Adventure Ultimate features our TrailBreaker ski designed to provide legendary on-trail performance, consistent off-trail performance and the best backing up capability we've ever put in a ski.
  • MANEUVER CONFIDENTLY IN VARYING SNOW CONDITIONS: The High-Clearance IFS is designed for less drag when breaking trail or backing up, so you can confidently navigate to the cottage, ice fishing destination, and more.
  • The TITAN is built to take you on-trail or off-trail with confidence and agility.

Heavy-Duty Performance

  • RIDER-FIRST DESIGN & EFFORTLESS CONTROL: The TITAN on the Matryx platform is built for work and play. The Matryx platform delivers a new level of comfort whether on the trails or deep snow.
  • CONFIDENCE-INSPIRING IN VARYING SNOW CONDITIONS: The patent-pending BackTrak20 Rear Suspension is the next-generation of articulated rear suspension. Designed with revised geometry to climb on top of the snow, the BackTrak20 dominates in forward or reverse.
  • POWER FOR YOUR RIDING STYLE: Choose the ProStar S4 4-stroke engine for smooth throttle response, easy ownership, and increased fuel efficiency. Or, choose the powerful 850 Patriot for towing heavy loads or tackling deep snow.
  • TITAN Adventure Ultimate is designed to break trail, haul and tow gear, and get the job done with the most premium features for added comfort and capability, including the standard TITAN cargo box, 7S Display powered by RIDE COMMAND, and the easily removable TITAN passenger seat. The TITAN lineup from Polaris features a 20" wide track for maximum flotation and traction.

Ultimate Capability and Comfort

  • NAVIGATE EASILY AND STAY PREPARED: The TITAN Adventure Ultimate features the 7S Display powered by RIDE COMMAND, with full GPS capabilities to enable you to explore further with trail maps, waypoints for worksites or fishing destinations, and more even when you're in the most remote destinations without cell reception.
  • MAXIMUM VERSATILITY: TITAN Adventure Ultimate features a standard tow hitch to tow up to 1,200 lbs. and a work light for tackling heavy-duty tasks day or night. Plus, an easily removeable passenger seat lets you ride with or without a friend.
  • INCREASED WIND PROTECTION: Widetrack riders know the conditions aren't going to dictate where or when you ride. With a standard tall windshield, or swap with an accessory Alaskan Windshield for even more comfort and coverage, wind isn't going to blow your day.
  • With an ideal blend of work and play features, the TITAN Adventure is built to help you tackle winter tasks including an integrated rack that can pack up to 125 lbs. of gear and supplies, and a TITAN cargo box that has 30 gallons of storage.
