The 300R marks the new top of Kawasaki’s off-road line, and as with the other two models announced, it’s brand new throughout. The liquid-cooled, fuel-injected 292cc single has a 78 x 61.2mm bore and stroke, 11.1:1 compression ratio, and lightweight piston, pin, and connecting rod, with a Nikasil plating on the cylinder as well.
