Description
Bred from a rich history of experienced belt builders, the Dayco XTX belt is specifically engineered to maximize the performance of the most extreme, high horsepower snowmobiles. Beating the competition on the race course is just one of many aspects that sets the XTX belt apart from its competition. Specially formulated high temperature Polymer along with the highest level of engineered reinforcement proves to perform better in belt operating temperature and efficiency than leading competitors. Its innovative break-through design of deeper cogs on top and rounded cogs on the bottom yield the advantages of ultimate flexibility and longer belt life while being a better alternative to the original equipment belt.

Vehicle Information
Yamaha Phazer XTX 500 Snowmobile (2014-2018)
The Yamaha Phazer XTX 500, produced from 2014 to 2018, was a versatile crossover snowmobile designed for both groomed trails and off-trail exploration. It was powered by a consistent 499cc, 4-stroke, 2-cylinder, liquid-cooled Genesis Sport Performance engine, delivering 80 horsepower. This engine was known for its quick acceleration and responsive throttle, making the XTX a popular choice in its segment. Throughout its production run from 2014 to 2018, the Phazer XTX 500 maintained its core specifications without significant mid-cycle generation or engine changes. The 499cc, 80 hp engine remained consistent. The XTX was introduced in 2014 as a distinct crossover trim, featuring a 144-inch track with 1.5-inch lugs, alongside other Phazer models like the trail-oriented RTX and the mountain-specific MTX. The XTX itself represents the crossover configuration, and no sub-trims were noted for it within this period. The Phazer line was discontinued after the 2018 model year.
