Vehicle Information
Honda XR400R Dirt Bike (1996-2004)
The Honda XR400R, produced from 1996 to 2004, was a popular off-road motorcycle known for its robust and consistent design. It was powered by a 397cc air-cooled, dry-sump, single-cylinder, four-stroke engine, paired with a five-speed gearbox. This reliable engine, featuring Radial Four-Valve Combustion Chamber (RFVC) technology, typically produced around 34 horsepower, ensuring consistent performance. The model maintained remarkable technical consistency from 1996 to 2004. The core engine design and transmission remained largely unchanged throughout its production run. Only minor cosmetic updates, such as gas tank logos, seat colors, or racing-inspired graphics, were introduced over the years, without affecting fundamental specifications or mechanical parts. There were no significant generation breaks or new trim levels introduced for the XR400R during this period. FAQ:
