The Kawasaki FD620D DFI is a 0.6 l (617 cc, 37.7 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 FD620D DFI has an 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 FD620D DFI uses a full pressure lubrication system with spin-on oil filter and dual element air cleaner.
The Kawasaki FD620D DFI develops 19.0 PS (14 kW; 18.7 HP) at 3,600 rpm and 44.6 Nm (4.5 kg·m; 32.9 ft·lb) at 2,200 rpm of torque. Bore and stroke are 76.0 mm (2.99 in) and 68.0 mm (2.68 in), respectively.
