Fuel injection
The Z1300 had six cylinders, water cooling, and shaft drive. The undersquare stroke of and bore of kept the engine width acceptable, but the high piston speed limited the maximum rpm figure. During its ten-year production run, fuelling was switched from carburetors to electronic fuel injection and suspension was upgraded to air systems front and rear. Fuel injection system was adopted primarily to improve fuel consumption, but as a bonus were increased power and torque.
