The Honda XR series is a range of four-stroke off-road motorcycles that were designed in Japan but assembled all over the world.
Some of the XR series came in two versions: R and L. The R version bikes were enduro machines designed for off-road competitive riding. They were fitted with knobby off-road tires and were not always street legal. The L version models were dual-sport trailbikes, fitted with lights, indicators, horn, and street-legal tires.
