Vehicle Information
Polaris Xplorer 400 ATV (1995-2002)
The Polaris Xplorer 400, produced from 1995 to 2002, was a versatile ATV known for its robust two-stroke engine and capable four-wheel-drive system. It was powered by a liquid-cooled, single-cylinder engine with a precise displacement of 378.7 cc (often rounded to 378 cc or 395 cc), which remained largely consistent throughout its production run. While the core engine did not undergo a major generation break, notable evolutions occurred. The "400L" designation (for "liquid-cooled") was used from 1995 to 1997, before the model was simply referred to as "Xplorer 400" from 1996 to 2002. The year 1996 saw the introduction of significant improvements, particularly to the cylinder, piston, rear shock, and front hub seals. All models featured an on-demand 4x4 system and an automatic PVT transmission. FAQ:
