Riding the Kawasaki ZX-6R

The ZX-6R's all-new 599cc power plant received the most attention of any major component. It has an aluminum cylinder block that now features liner-less, electroplated bores (same as the ZX-9R) which are reported to save weight as well as improve heat dissipation. The cylinders themselves have a redesigned "pentroof" combustion chamber that features an increase in compression from 11.8:1 to 12.8:1 the result of which requires the use of at least 90-octane fuel.
