The Kawasaki KLR650 is a dual-purpose motorcycle intended for use on both paved and unpaved roads. It has been a long-standing model in Kawasaki's lineup, having been introduced in 1987 and remaining almost unchanged through the 2007 model.

 

Kawasaki, in releasing the much-anticipated 2008 model, introduced the first significant redesign of the KLR650 since its inception.

The KLR650 is heavier than specialized off-road dirt bikes, but it can handle most conditions when ridden carefully by a skilled rider. Its 4-stroke DOHC dual-counter balanced, single-cylinder, water-cooled engine develops a claimed 44hp at the crank; typical measurements at the rear wheel are 35 horsepower. Typical fuel economy is 45 to 60 miles per U.S. gallon (3.9 to 4.7 L/100 km). It has a claimed 6.1 gallon (23 litre) fuel tank and a top speed of approximately 105 mph (160 km/h).

 

This motorcycle is considered by many to be the best all-round motorcycle ever made, with legions of fans and websites for support & add-ons. The KLR is widely used as an inexpensive adventure/touring bike. The addition of luggage and personalized modifications (GPS, heated handgrips, larger windscreens) make it more functional on long trips.

KLRs have been ridden to the Arctic, across North and South America, and throughout Europe, Africa, and Asia, as well as on full global circumnavigation rides (e.g., Dr. Gregory Frazier in 2001-2002[1]). Nicknames include "Swamp Thing" "The Mule" and "The Tractor."

Note: While advertised capacity is 6.1 gallons, usable gas tank capacity is approximately 5.6 gallons including reserve, because approximately one half gallon of fuel sits below the top of the petcock intake tube within the tank, or on the other side of the main frame member, which divides the lowest portion of the tank into two lobes (the petcock draws only from one of these two lobes). In an emergency, this extra fuel can be utilized by tipping the bike on its side (nearly horizontal) allowing the fuel to slosh from one side of the tank to the other. This yields a maximum range of approximately 250-300 miles between fill-ups, depending on riding conditions.
