The Kawasaki KLR650 is a 652 cc dual-sport motorcycle intended for both on-road and off-road riding. It was a long-standing model in Kawasaki's lineup, having been introduced in 1987 to replace the 564 cc 1984–1986 Kawasaki KLR600, and remaining almost unchanged through the 2007 model. The 2008 model was the first significant redesign of the KLR650 since its inception. It was built with a 652 cc four-stroke, DOHC, dual-counterbalanced, single-cylinder, liquid-cooled engine. The second significant redesign in 2022 added new features such as electronic fuel injection and an anti-lock braking system. 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. The bikes have been used for long distance and intercontinental trips, as well as full global circumnavigation rides e.g., by Dr. Gregory Frazier in 2001 and 2002.
