Yamaha FZS600 Fazer Service Manual (1998)

Yamaha introduced the FZS600 Fazer as a new 1998 European-market middleweight, first shown at the Paris Show in September 1997. Yamaha positioned it between the practical Diversion 600 and the more focused YZF600R Thundercat, aiming to combine strong sport performance with everyday usability and lower running costs. Yamaha's original launch announcement described it as a new 600cc sports model using the basic engine architecture of the YZF600R, retuned for stronger low- and mid-range response. Yamaha's 1997 FZS600 launch release documents the model's original concept and specifications.

The first-generation Fazer uses a 599 cm³ liquid-cooled, four-stroke DOHC inline-four with a 62.0 x 49.6 mm bore and stroke and a 12.0:1 compression ratio. Fuel is supplied by four Mikuni BSR33 carburetors, and power is transmitted through a wet multi-disc clutch, six-speed constant-mesh gearbox and chain final drive. In this service manual the model is identified by Yamaha code 5DM1. The engine was derived from Yamaha's YZF600R platform but tuned around a broader road-going power delivery, making the FZS600 a carbureted 600cc all-round sport motorcycle rather than a supersport-focused machine.

The chassis uses a steel double-cradle frame, 41 mm conventional telescopic fork, rear link-type swingarm suspension and 17-inch cast wheels. Braking hardware includes dual 298 mm front discs and a 245 mm rear disc. With an 18-liter fuel tank, half fairing, upright ergonomics and practical road equipment, the Fazer was intended to handle commuting, touring and fast back-road riding within the same package. Yamaha later noted that the FZS600 became a major European success, selling more than 16,000 units in 1999 and nearly 83,000 units in Europe by the end of 2002.

The FZS600 remained the basis of Yamaha's middleweight Fazer line until the fully redesigned FZ6-S Fazer appeared for the 2004 model year. Yamaha described that later model as the first full model change in six years, confirming the original FZS600's 1998 launch and its role as the first generation of the modern Fazer 600 line. Yamaha's FZ6 launch history provides that generation context. This factory service manual covers the original 1998 FZS600 Fazer and includes workshop procedures for the engine, cooling system, carburetors, chassis, electrical systems and troubleshooting.
