The Polaris Indy 400, Indy 400 SKS, Indy 600, and Indy Sport snowmobiles were produced by Polaris Industries in 1987. These models were part of the Indy line, known for their reliable performance and versatility. The Indy 400 was powered by a liquid-cooled, 399cc twin-cylinder engine, providing a balance of power and fuel efficiency. The SKS version, short for "Suspension Kit Special," featured a more advanced suspension system designed for off-trail riding and challenging terrain. The Indy 600, on the other hand, boasted a larger, 599cc twin-cylinder engine, delivering more horsepower and torque for those seeking a thrilling ride. The Indy Sport, with its smaller engine and more affordable price point, aimed to attract a wider range of riders, particularly those new to the world of snowmobiling.

These Indy models were known for their innovative features and advancements in snowmobile design. The 1987 models typically featured a durable steel frame, a reliable track system, and a comfortable rider position. They incorporated advanced suspension technologies, such as the Polaris Independent Front Suspension (IFS), which provided improved handling and a smoother ride. The Indy 400 and 600 models were often equipped with a "SureGrip" track, designed to provide superior traction on various snow conditions. The Indy Sport, while offering a simpler design, still maintained the basic reliability and performance expected from a Polaris snowmobile. These models played a significant role in solidifying Polaris's reputation for quality and innovation in the snowmobile industry, setting the stage for future advancements in performance and technology.
