Vehicle Information
Polaris Trail Blazer 250 ATV (1990-2006)
The Polaris Trail Blazer 250 was a popular sport ATV produced from 1990 to 2006. It was powered by a 244cc (often marketed as 250cc) single-cylinder, two-stroke, air-cooled engine, paired with a Polaris Variable Transmission (PVT) with reverse. Throughout its production, it largely maintained a single trim level, the "Trail Blazer 250." A significant change occurred early in its production run: the engine underwent a "detuning." Earlier models (late 1980s/early 1990s) featured a 38mm carburetor and modified cylinder porting, producing over 30 horsepower. By 1994 and for most of the 1990-2006 period, the engine was detuned with a 30mm carburetor and smaller cylinder ports, resulting in approximately 22 horsepower. Despite this power reduction, the fundamental engine design remained consistent. While a "Gen III" body style is mentioned, specific details for chassis changes within the 1990-2006 range are not extensively documented. FAQ:
