Suzuki GSX1300BK B-King Service Manual (2008)

Suzuki brought the B-King concept into production for the 2008 model year as the GSX1300BK, creating a large-capacity naked roadster with unusually aggressive styling and superbike-level mechanical hardware. Suzuki's 2008 annual report states that the B-King concept model was finally made available to the market alongside the redesigned Hayabusa 1300, GSX-R600/750 and Boulevard C109R. The production motorcycle retained the concept's muscular proportions, large tank-area bodywork and distinctive twin under-seat exhaust treatment while using a road-focused upright riding position rather than full sportbike bodywork.

The GSX1300BK uses a 1,340 cm³ liquid-cooled DOHC inline-four with an 81.0 × 65.0 mm bore and stroke and a 12.5:1 compression ratio. The factory manual documents electronic fuel injection, secondary-throttle control, extensive ECM self-diagnosis and multiple sensor circuits. Power passes through a wet multi-plate clutch and six-speed constant-mesh transmission to a 43/18 chain final drive. These specifications place the motorcycle firmly in the 1340cc naked hyperbike category, combining the engine performance of Suzuki's large sport machines with an unfaired chassis and wider handlebar layout.

The chassis is substantial enough to manage the engine output while preserving road usability. Factory specifications list a 1,525 mm wheelbase, 805 mm seat height and dry mass of approximately 235 kg, or 236 kg for the U.S. specification. Suspension uses a conventional sport-oriented layout with a telescopic front fork and link-type rear system, while braking is handled by dual front discs and a single rear disc. The manual also documents hydraulic clutch service, drive-chain adjustment, suspension diagnosis, steering, wheel and tire procedures and full brake-system servicing.

Electronic systems are a major part of the B-King platform. The service publication includes detailed fuel-injection diagnostics, ECM terminal data, fault codes, sensor testing, charging and starting systems, lighting, combination-meter functions and complete wiring diagrams for the different market specifications. Suzuki's official 2008 annual report provides launch context for the production B-King, while related manuals are organized in the Suzuki GSX1300BK manual catalog.

This listing is specifically for the 683-page GSX1300BK K8 factory service manual. Although the PDF filename and copyright date reference 2007, the factory identification is explicitly 2008-model, with K8 variants for the U.K., EU, U.S., Australia, Canada and California. No later K9-K12 supplementary sections are present, so verified applicability is 2008 only.
