Vehicle Information
Honda Foreman 400 ATV (1995-2003)
The Honda Foreman 400 (TRX400FW), produced from 1995 to 2003, was a robust and reliable utility ATV. It featured an air-cooled, OHV, single-cylinder, four-stroke engine, consistently reported with a displacement of 395cc or 397cc. A key innovation from 1995 was Honda's longitudinal engine design, which positions the crankshaft perpendicular to the axles. This design minimizes frictional losses, reduces weight, lowers the center of mass, and enhances ground clearance. Throughout its production run from 1995 to 2003, the Foreman 400 was offered as a single, full-time 4x4 model. There were no distinct trims like "S" or "ES" for this model. The core engine design and displacement remained consistent across all model years. Innovations such as the Electric Shift Program (ESP) or the TraxLok switchable 2WD/4WD system were introduced on other Foreman models, like the Foreman 450, and not on the Foreman 400 during this period. Q: How do I ensure this product fits my specific Honda Foreman 400?
