Vehicle Information
Yamaha WR400F Dirt Bike (1998-2000)
The Yamaha WR400F, produced from 1998 to 2000, was a pioneering four-stroke enduro motorcycle renowned for its powerful engine and exceptional off-road capabilities. This model featured a single-cylinder, four-stroke, DOHC, 5-valve engine with a 399 cc displacement across all years. It was offered as a single "Enduro" or "Off-road" model, without distinct sub-trims. The WR400F saw significant evolution during its initial run. Introduced in 1998, it was derived from the YZ400F motocrosser. In 1999, it received updates to its suspension and engine calibration, alongside carburetor modifications for improved starting. The 2000 model year brought substantial changes, including a slimmer seat and fuel tank (reducing capacity to 8 liters), making the bike 2.5 kg lighter. Other enhancements included faster suspension damping, a stiffer lower triple-clamp, and a repositioned steering head to shorten the wheelbase, alongside further chassis, ignition, and engine refinements.
