Kawasaki ZX10R 2004 Engine Specification.
- Liquid-cooled, 998cc four-stroke, inline four-cylinder engine utilizes stacked layout used for compact dimensions, contributing to the ZX-10R’s narrow profile
- One-piece cylinder/crankcase saves weight and is more rigid
- Forged pistons have flat top for compact combustion chamber
- Cams machined from chromoly steel billet and surface treated with soft nitride for light weight and durability
- Tappet surfaces treated with soft nitriding to help prevent wear
- Intake and exhaust valves use single springs with oval cross sections to lower overall engine height
- Flow analysis used to design cylinder head, maximizing engine breathing at high rpm
- All-titanium four-into-one exhaust system includes butterfly valve to enhance low-rpm power
- Oval-shaped aluminum muffler with internal titanium parts reduces noise and includes honeycomb catalyzer to reduce emissions
- Electronic fuel injection with sub-throttle assembly and 43mm throttle bodies provide best power characteristics and ridability
- High-speed generator is clutch driven and is positioned behind the cylinder bank to reduce engine width
- Liquid-cooled oil cooler helps to maintain consistent oil temperatures
- Sloshing analysis used to design internal structure of oil pan, reducing windage and helping to maintain low oil temperatures
- Magnesium engine covers reduce overall dry weight
