The new 2012 Kawasaki Ninja ZX-10R ABS design is compact, narrow and lightweight. Camshafts, crankshaft and pistons designed to complement the engine’s prodigious power production. The ZX-10R ABS large intake valves, camshaft profiles and port shapes help maximize power production and smooth power delivery. The highly advanced 2012 Ninja ZX-10R has just met its match: The 2012 Ninja ZX-10R ABS. Built with the same cutting-edge sport bike technology, much of it right off the MotoGP circuit, the ZX-10R ABS has an important advantage: anti-lock braking. At first, anti-lock braking might seem a touch out of place on a purebred sportbike. But this system was designed from the start to provide maximum performance. And when you consider the many safety- and control-oriented benefits provided by the amazing electronic and hardware technology available today, it begins to make a lot of sense.
Think of it: You’re braking for a blind, decreasing-radius corner after a long day of sport riding. Shadows are long and you’re tired, so you don’t notice a patch of sand until it’s too late to correct. But instead of tucking as you continue braking through the sand, your front tire maintains most of its traction, as the anti-lock braking system intervenes until the surface improves allowing you to arc gracefully into the corner, a little wiser and a lot more intact physically than you might have been riding a non-ABS motorcycle. Kawasaki calls its anti-lock system KIBS or Kawasaki Intelligent anti-lock Brake System. The use of “intelligent” is apropos, too, considering just how smart the new KIBS is. It all starts with the smallest and lightest ABS unit ever built for a motorcycle, one Bosch designed specifically with sport bikes in mind. It’s nearly 50 percent smaller than current motorcycle ABS units, and 800 grams lighter, adding only about 7 pounds of weight compared to the non-ABS machine, a pound of which is accounted for by the larger battery.
KIBS is a multi-sensing system, one that collects and monitors a wide range of information taken from wheel sensors (the same ones collecting data on the standard ZX-10R for its S-KTRC traction control system) and the bike’s ECU, including wheel speed, caliper pressure, engine rpm, throttle position, clutch actuation and gear position. The KIBS’s ECU actually communicates with the bike’s engine ECU and crunches the numbers, and when it notes a potential lock-up situation, it tells the Bosch ABS unit to temporarily reduce line pressure, allowing the wheel to once again regain traction.
Aside from this system’s ultra-fast response time, it offers a number of additional sport-riding benefits, including rear-end lift suppression during hard braking, minimal kickback during ABS intervention, and increased rear brake control during downshifts. The high-precision pressure control enables the system to avoid reduced brake performance (sometimes seen on less advanced systems), maintain proper lever feel and help ensure the ABS pulses are minimized.
The rest of the 2012 Ninja ZX-10R ABS is equally advanced. Complete with a powerful engine and lightweight chassis, it also boasts a highly advanced and customizable electronic system that allows riders of all skill levels to harness and experience the ZX-10R ABS’s amazing blend of power and razor-edge handling. The system is called Sport-Kawasaki Traction Control. Motorcyclists have forever been challenged by traction-related issues, whether on dirt, street or track. Riders who can keep a rear tire from spinning excessively or sliding unpredictably are both faster and safer, a tough combination to beat on the racetrack. And when talking about the absolute leading edge of open-class sport bike technology, where production street bikes are actually more capable than full-on race bikes from just a couple years ago, more consistent traction and enhanced confidence is a major plus.
The MotoGP-derived S-KTRC system works by crunching numbers from a variety of parameters and sensors – wheel speed and slip, engine rpm, throttle position, acceleration, etc. There’s more data gathering and analysis going on here than on any other Kawasaki in history, and it’s all in the name of helping racers inch closer to the elusive “edge” of maximum traction than ever before. The S-KTRC system relies on complex software buried in the ZX-10R’s Electronic Control Unit (ECU); the only additional hardware is the lightweight speed sensors located on each wheel.
Unlike the KTRC system on Kawasaki’s Concours 14 ABS sport tourer, which primarily minimizes wheel slip on slick or broken surfaces as a safety feature, the S-KTRC system is designed to maximize performance by using complex analysis to predict when traction conditions are about to become unfavorable. By quickly but subtly reducing power just before the amount of slippage exceeds the optimal traction zone, the system which processes every data point 200 times per second maintains the optimum level of tire grip to maximize forward motion. The result is significantly better lap times and enhanced rider confidence exactly what one needs when piloting a machine of this caliber.
The potent ZX-10R engine is a 16-valve, DOHC, liquid-cooled inline-four displacing 998cc via 76 x 55mm bore and stroke dimensions. This powerplant is tuned to optimize power delivery, center of gravity and actual engine placement within the chassis. Torque peaks at an rpm range that helps eliminate power peaks and valleys that make it difficult for racers and track-day riders to open the throttle with confidence. Large 47mm throttle bodies help with throttle control. Secondary fuel injectors enhance power output and power characteristics at high rpm; the lower injectors are always on, while upper injectors come on as needed according to degree of throttle opening and engine rpm. An Idle Speed Control (ISC) valve on the throttle body unit automatically adjusts idle speed, contributing to easier starts and off-idle throttle response
