Kawasaki W800 Service Manual (2011–2016)

The Kawasaki W800 was introduced for 2011 as the latest evolution of Kawasaki's long-running W-series heritage. Kawasaki's launch announcement traced that line back to the W1, first shown in the mid-1960s, and positioned the W800 as a modern motorcycle intended to reproduce the appearance and riding character of a classic machine. The W800 also followed the later W650, continuing the vertical-twin theme with traditional proportions, large-diameter wheels, extensive polished metalwork and a simple roadster layout.

At its center is a 773 cc air-cooled fuel-injected parallel twin with a long-stroke 77.0 × 83.0 mm bore and stroke, SOHC valve gear and 8.4:1 compression ratio. The service manual specifies Keihin TTK34 dual throttle bodies and electronic fuel injection, with 35 kW (48 PS) at 6,500 rpm and 60 N·m at 2,500 rpm on the main specification. That low-speed torque peak reflects the model's emphasis on relaxed road use rather than high-rpm performance. Engine lubrication is wet-sump, with a total oil capacity of 3.2 L.

Power passes through a wet multi-disc clutch and five-speed constant-mesh return-shift gearbox to a chain final drive with a 2.467 reduction ratio. The chassis uses a tubular double-cradle frame with 27-degree rake, 108 mm trail and a 1,465 mm wheelbase. The W800 rides on a 100/90-19 front tire and 130/80-18 rear tire, with a conventional telescopic fork offering 130 mm travel and twin-shock swingarm rear suspension with 106 mm travel. Braking combines a single front disc with a rear drum. Factory dimensions include a 790 mm seat height, 14 L fuel tank and 217 kg curb mass.

Kawasaki's official W800 launch announcement documents the model's W-series lineage, 773 cm³ air-cooled twin and vintage-oriented design, while Kawasaki's 2011 W800 Owner Center page confirms the EJ800AB model family. The uploaded PDF is the sixth edition dated July 17, 2015; its Model Application page lists EJ800AB through EJ800AG for 2011–2016 under part number 99924-1441-06. Because 2017 is not listed, the previous 2017 tag is removed. For related documentation, browse the Kawasaki W800 manual category.
