The M66-3R* features a deep 2.62″ lug pattern with center porting that is designed to work in a wide range of snow conditions. The “Pop-Up” flexible center lugs get you up and on top of the snow and prevent trenching. Great handling and traction in wet or packed snow with excellent performance when side hilling. Durable 2 ply construction gives a big bite in backcountry conditions. The M66-3R* allows beginners to tackle new terrain and opens up endless choices for the experienced mountain rider.
*Note: The 3R denotes the center ported track which allows bolt-on application to all Ski-doo and Polaris models. Some Polaris modes use an anti-ratchet center driveshaft sprocket so the center ports allow bolt-on application. The 154″ track is the same as Polaris 155″ and will bolt right on; they round up the length for sales marketing.
