Built around Suzuki's naked motorcycle platform, the 2023 Suzuki GSX-8S utilizes a 776 cc (47.4 cu in) liquid-cooled twin, four-stroke layout. Internal engine geometry specifies a bore and stroke of 84.0 x 70.0 mm (3.3 x 2.8 inches) with a 12.8:1 compression ratio.
On the scales, the GSX-8S measures 202 kg (445 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.2 L/100 km provides an estimated theoretical range of roughly 333 km (207 miles) between fill-ups.
