About the Suzuki GSX-R750

Suzuki revised the GSX-R750 again for 2008, maintaining the model's long-standing 750-class supersport formula while adding electronic and engine-management refinements. Suzuki's official GSX-R750 digital archive describes the 2008 version as a further-enhanced model based on the newly developed GSX-R600, with changes aimed at preserving the GSX family's balance of weight, size and performance.

The GSX-R750 uses a 750 cm³ liquid-cooled DOHC inline-four with a 70.0 × 48.7 mm bore and stroke and a 12.5:1 compression ratio. The factory service specification lists electronic fuel injection, a wet multi-plate clutch and a six-speed constant-mesh transmission. Final drive is by chain with a 45/17 reduction ratio. Suzuki's archive notes the adoption of eight-hole multi-hole fuel injectors, a larger muffler and Suzuki Drive Mode Selector for the 2008 generation.

The chassis remained compact and track-oriented. Factory specifications list a 1,405 mm wheelbase, 810 mm seat height and dry mass of 167 kg for most markets, with 168 kg specified for California. Suspension uses fully adjustable front and rear systems, while braking is handled by twin front discs and a single rear disc. These characteristics define the motorcycle as a 750cc fuel-injected supersport motorcycle designed around low mass, high engine speed and precise chassis response.

The 2008 update also expanded the bike's electronic service requirements. The manual includes detailed ECM terminal information, fuel-injection self-diagnosis, secondary-throttle actuator and sensor testing, charging and starting systems, combination-meter diagnostics and market-specific wiring diagrams. Suzuki's official archive places this model between the 2006 redesign and the later 2011 GSX-R750 generation, making K8 an identifiable technical step rather than simply a carry-over year.

This listing is specifically for the 659-page GSX-R750 K8 factory service manual. The publication identifies the motorcycle as the 2008 model and contains no K9 or L0 supplementary service sections, so verified applicability is 2008 only. Related factory publications are organized in the Suzuki GSX-R750 manual catalog.
