2004 Kawasaki KLX400R Off-Road Model
Off-road motorcycling, for many enthusiasts, represents the very essence of motorcycling as a whole. Every ride is a mini-adventure; the opportunity to explore the woods, hills, trails, canyons and deserts that beckon throughout the normal work week.

The KLX400R is designed for such off-road excursions. With its electric start four-stroke engine, long-travel suspension and aggressive knob tires, it is built to conquer the toughest enduro trails or provide a leisurely trail ride.

One push of a button fires up the KLX400.s lightweight 6.5 amp electric starter. The responsive power stems from a double overhead cam, four valve, liquid-cooled dry sump engine that boasts rapid throttle response at all rpm. A nickel-silicon-phosphorous plated cylinder provides excellent heat transfer properties and is host to a forged aluminum piston, which receives oil cooling through a crankcase oil jet. A twist of the throttle demonstrates that torque is on-tap from the low-end to the mid-range, and continues all the way up the powerband. Crisp and quick throttle response is provided by a Keihin FCR39 carburetor, which drinks from a long-range 2.6-gallon fuel tank.

For easy maintenance, a cable-operated clutch with a separate outer cover operates with the compact five-speed transmission. Equipped with a gear for any off-road situation, the KLX400R.s transmission can handle anything from tight, slimy and rocky terrain to high-speed hard pack.

Wrapped around the responsive engine is an equally responsive chassis. With a dry weight of just 249 pounds, the KLX400R is slim, nimble and easy to throw around the trail. Bolted to the chromoly steel frame is an aluminum subframe that provides a skeleton for a smooth transition between tank, seat and bodywork. Giving the KLX400R a plush ride is the 49mm long-travel cartridge fork, which features rebound damping and adjustable spring preload. A lightweight aluminum swingarm and rear shock with high/low-speed rebound and compression damping adjustability complement the fork and overall chassis package. Prime stopping power comes from front and rear hydraulic disc brakes.

Finishing touches to the KLX400R include off-highway lighting via a 55-way headlight and LED-type taillight, durable steel foot pegs, aluminum rims and hubs and a U.S. Forest-approved spark arrestor. (2003 model Suggested Retail: $5,499 for reference only)
