Unable to meet new emissions standards, Kawasaki W650 production ended in 2008.

The W650 has a long-stroke engine of 72 mm bore x 80 mm stroke with an anti-vibration balance shaft and modern electronics. An air-cooled SOHC, 8-valve vertical twin 676cc engine, 360-degree crankshaft design, 4.0-gallon fuel tank, and double-cradle pattern with a beefy square backbone frame concealed under the tank.

General information about the 2001 Kawasaki W650

The W650’s twin cylinder, air-cooled 676cc engine churns out plenty of responsive low- and mid-range power, due in part to its long-stroke 360 degree crankshaft that has both pistons rising and falling together. A modern four-valve cylinder head helps give the W650 a healthy top-end, too. The valves are actuated by a single overhead camshaft that is driven by a hypoid gear, where the bevel shaft is offset to one side of the gears for less noise and friction, and increased durability.

The pair of constant velocity carburetors are equipped with the Kawasaki Throttle Responsive Ignition Control (K-TRIC) throttle position sensor. Connected to the Digital Ignition system, K-TRIC varies ignition timing according to throttle position and engine rpm so that the ignition compensates for differing engine loads for crisp throttle response and better fuel efficiency.

The W650’s chassis design is clean and simple. A traditional double-cradle frame uses a hefty square-section backbone for rigidity. A half-degree increase in the steering angle plus a 2mm larger axle and new front hub featuring larger bearings improve handling. A steel swingarm and twin shocks with adjustable preload provide the rear suspension, while the ride up front has been improved with new fork springs and revised rebound and compression damping. Braking power is supplied by a 300mm front disc and rear drum.
