Vehicle Information
Polaris Trail Blazer 400 ATV (2003)
The 2003 Polaris Trail Blazer 400 was a sport ATV renowned for its powerful 378cc single-cylinder, 2-stroke engine, delivering approximately 39 horsepower, paired with an automatic PVT (Polaris Variable Transmission). This model was celebrated for its blend of power and agility, making it a popular choice for enthusiasts. For the 2003 model year, the Trail Blazer 400 was offered as a single standard model without distinct trim levels. There were no mid-cycle generation or engine changes specifically for the 2003 Trail Blazer 400; it maintained its robust 378cc two-stroke engine. The primary distinction within the Trail Blazer line during this period was between the 400cc and 250cc engine sizes. Notably, the 400cc model featured a Rear Fox shock, a premium component not found on the 250cc version, enhancing its performance and ride quality. While later models, starting around 2004, saw significant engine changes (e.g., a shift to a 329cc four-stroke engine), these do not apply to the 2003 400cc model. FAQ:
