The reason this Nytro carries the “1.75” label comes from the usage of an all-new Camoplast®-supplied rubber track with a 1.75 lug profile. Yamaha and Camoplast® have worked together in the past to help evolve the world of snowmobile traction. The Ripsaw® track appeared on Yamaha® sleds first. The two companies worked up ideas for getting up tall mountains and running through deep powder. Now the two companies have combined talents to rethink what crossover riders really need. This high performance crossover sled is equally at home on and off the trails. The Camoplast® Back Country track gives you the versatility to ride both on and off trail without compromise. The 1.75-inch lugs grab snow for great acceleration in powder and on packed trail. The unique design also gives just the right amount of lateral slide for fun trail cornering as well.
