I have a 2009 Yamaha Nytro XTX. It is the Yamaha crossover snowmobile so it has the 144" track on it. I spring ordered it, and had the dealer put on a taller 1.5" track. This still has the reminder of the factory 3 year warranty included! All the work was done at the dealer before i purchased it. Also installed was a 2 inch handlebar riser. Sled has 584 miles put on it, all of which were put on in good Michigan snow conditions. The sled has been really well cared for and is in mint condition. No rips or torn lugs in the track, no scratches or chips in the hood, all plastics and tunnel are spotless, no scratches on the skis. Always moved in an enclosed trailer and stored in a heated garage. 7500 obo. Please call me at 763-443-4527 with any questions - Thanks, Brandon
