The engine features more aggressive cams actuating 1mm-larger intake valves, with the cylinder head sporting new intake and exhaust porting, and lighter pistons pushing a higher 13.0:1 compression ratio. The crankshaft drives a new secondary counterbalancer, and is positioned slightly higher in relation to the main output shaft for better mass centralization. A new cassette transmission permits gear ratio changes (seven different accessory gearsets will be available) without draining the engine oil.
Up top, the repositioned ram-air intake duct (closer to the highest point of pressure on the fairing nose) funnels into a larger airbox/air filter setup. The new Keihin TTK47 fuel injection system sports larger 47mm throttle bodies (versus the old 43mm units). Down below, exhaust gases are cleaned up courtesy of a 2.6-pound-lighter system sporting a larger stainless steel under-engine chamber equipped with dual 300-cell catalyzers.

The all-new aluminum twin-spar frame shifts weight bias forward slightly with a 0.5-degree steeper rake (but longer trail) combined with a 20mm-longer swingarm. Showa’s BPF (Big Piston Fork) makes its way to the ZX-10R after debuting on the ZX-6R in ’09, with the rear shock mounted in a horizontal fashion above the swingarm with a reverse linkage. New three-spoke wheels are lighter, and the front brake calipers are slightly changed, with all four pistons measuring 30mm (instead of the previous staggered 32/30mm setup).
The usage of wheel speed sensors has also allowed Kawasaki to develop its new KIBS (Kawasaki Intelligent Braking System), claimed to be the world’s smallest and lightest ABS unit at just six pounds—with 2.3 pounds of that weight coming from the larger battery required to power the unit. Besides monitoring wheel speeds, the KIBS also analyzes brake system hydraulic pressure, throttle position, gear selection, engine rpm, and clutch actuation to decide how much and when to intervene at each wheel. The system is claimed to be able to detect rear wheel lift under aggressive braking without the use of gyro sensors; and its cycling rate is much quicker than conventional ABS, leading to better brake feel and feedback when the system is active. Unfortunately, Kawasaki had no ABS models at the press launch, so a review will have to wait until we get our hands on one for a full test.
