Rugged, fuel-efficient, value and more describe the hardy Kawasaki KLR 650 as it plows through the trails and steams over the asphalt. The massive 6.1 gallon fuel tank and the twin piston front disc brake with the single piston rear disc brake make for some interesting mountain and highway riding as you can stop for every squirrel and then keep going without a worry about how far you've gone since the last fuel replenishing stop.
