Vehicle Information
Polaris Indy Sport 340 Snowmobile (1987-1990)
The Polaris Indy Sport 340, produced from 1987 to 1990, is a classic snowmobile known for its reliable performance. It consistently featured a 339cc fan-cooled twin engine, equipped with two Mikuni VM30SS slide carburetors, typically producing around 36 horsepower. This model was a staple in the Indy line, which was notable for its Independent Front Suspension (IFS) introduced in 1980. Throughout its 1987-1990 production, the core Indy Sport 340 platform remained stable with no significant mid-cycle generation or engine changes. However, a "GT" trim was introduced, offering variations. From 1988, the Indy Sport GT became available, and by 1990, the Indy Sport GT 340 featured a longer 141-inch track with a 1.00-inch lug height, compared to the standard 121-inch track with a 0.72-inch lug height on the regular Indy Sport 340. These trim differences primarily affected ride characteristics and traction. FAQ:
