Vehicle Information
Polaris Sport 400 ATV (1994-1999)
The Polaris Sport 400, produced from 1994 to 1999, was a popular liquid-cooled, two-stroke ATV. It consistently featured a 378cc engine across all model years, known for its robust performance. The primary trim was the Sport 400L, with the 'L' likely denoting its liquid-cooled nature, though the 'L' was sometimes omitted in later years' documentation. Significant mid-cycle changes were implemented in 1996. These updates included a new cylinder, piston, rear shock diameter, fan motor, and front hub seals. The chassis also saw a redesign, with pre-1995 models utilizing an older style chassis. The transmission remained a Polaris Variable Transmission (PVT) with E-Z shift high and reverse throughout the production run, and the engine featured oil injection. FAQ:
