Vehicle Information
Polaris Indy Storm 750 Snowmobile (1993)
The 1993 Polaris Indy Storm 750 was a high-performance snowmobile, marking a significant introduction for Polaris. It featured an all-new, liquid-cooled, 744cc, three-cylinder Fuji engine. Available trims included the Indy Storm and Indy Storm SKS. The 1993 model represented an entirely new generation for the Storm lineup. Beyond the new 744cc engine, key advancements included its lower mounting for improved handling, the introduction of the Improved Transfer Rear Suspension (ITS) for better weight distribution, and various refinements to the Indy chassis, brake system, and seating. This 750cc engine was specific to 1993, as the Storm lineup transitioned to an 800cc engine for the 1994 model year. FAQ:
