Powerful 948 cm3 liquid-cooled, 4-stroke In-line Four engine has a quick-revving character and a strong mid-range hit that pulls strongly to the redline. Adding to rider exhilaration, a distinct intake note encourages you to twist the throttle. Silky smooth power delivery facilitates control while contributing to rider comfort and confidence. Power delivery is quite linear, but the engine spins up noticeably faster from about 6,000 min-1 onwards. Silky smooth response from mid-high rpm ensures excellent driveability. Lightweight and rigid, the pistons are formed using a unique casting process (similar to forging process) that sees unnecessary material removed and hollows created to achieve the ideal thickness (the same process used to form the Ninja H2/H2R pistons). This enables a light weight on par with forged pistons.
