Bore X Stroke:
VS700: 70.0 x 76.0 mm; VS750: 74.0 x 80.0 mm; VS800/S50: 83.0 x 74.4 mm (approximate, manual will confirm exact)
Compression Ratio:
Typically around 9.2:1 to 9.5:1. Manual will confirm exact figures.
Carburetion:
Typically Mikuni carburetors (e.g., VM series). Specific models may vary. The manual would detail jetting, adjustment, and overhaul.
Fuel Delivery:
Carburetor(s), with specifications for flow rates and adjustments.
Wheelbase:
Varies by model, but typically around 60-63 inches (1525-1600 mm).
Length:
Varies by model, typically around 90-94 inches (2286-2388 mm).
Width:
Varies by model, typically around 34-36 inches (864-914 mm).
Dry Weight:
Approximately 450-500 lbs (204-227 kg) depending on the specific model and configuration.
Crash Test Data:
Not applicable for motorcycles in the same way as cars; safety focuses on braking and handling capabilities detailed in the manual.
Braking System:
Front disc brake, rear drum brake (early models) or dual front disc brakes and rear disc brake (later models like S50). Manual covers inspection, pad/shoe replacement, fluid bleeding.
Frame Type:
Steel double-cradle frame. Manual covers frame inspection and any related repair procedures.
Oil Change:
Typically every 3,000-6,000 miles (5,000-10,000 km) or annually, depending on usage. Manual will specify exact intervals and conditions.
Spark Plug Replacement:
Typically every 6,000-12,000 miles (10,000-20,000 km). Manual provides specific plug types and gap settings.
Valve Clearance Check:
Typically every 12,000-18,000 miles (20,000-30,000 km). Manual details the procedure and required specifications.
Engine Oil:
Suzuki recommends specific viscosity grades (e.g., 10W-40 or 20W-50) and API classification (e.g., SG or higher). Manual will list exact specifications and capacities.
Shaft Drive Fluid:
Suzuki Gear Oil 80W-90 (or equivalent API GL-4). Manual confirms capacity and change intervals.
Coolant Type:
