The Kawasaki FD711D DFI is a 0.75 l (745 cc, 45.46 cu-in) V-twin 90° liquid-cooled 4-stroke internal combustion small gasoline motor with horisontal shaft, manufactured by Kawasaki Heavy Industries LTd., for general-purpose applications.
The FD711D DFI has OHV (overhead valve design); cast-iron cylinder liners; multi-port digital fuel injection; high-pressure transistorized fuel pump; flywheel magneto transistor ignition system; mechanical governor; low tone muffler and compact electronic control unit. The Kawasaki FD711D DFI uses a full pressure lubrication system with spin-on oil filter and dual element air cleaner.
The engine was equipped with solenoid shift-type electric starter and 12V-20A or 30A charging coil with a regulator.
The Kawasaki FD711D DFI produced 25.0 HP at 3,600 rpm of maximum horsepower. Cylinder bore and piston stroke are 78.0 mm (3.07 in) and 78.0 mm (3.07 in), respectively. Compression ratio rating is 8.1:1.
