Updated chassis geometry features slightly steeper rake (0.5 degree) and 3mm less. The result is more weight on the front wheel.
ELECTRONICS
Never in a million years did I think there would come a day that I’d say this, but, without question the most exciting feature of the new ZX-10R has nothing to do with the engine, chassis or anything else mechanical. It all comes down to a tiny black box and two sensors attached to each wheel. These are the primary components that make up the Sport-Kawasaki Traction Control (S-KTRC).
Motorcycle USA takes to the track with Kawasaki's fully redesigned Ninja ZX10R in our 2011 Kawasaki Ninja ZX-10R First Ride Video.
Four different modes are available based on rider preference or road conditions. Level 1 is designed for track use with racing tires. Level 2 is for general sport riding on either the street or racetrack, while Level 3 is for use in the wet or on slippery road surfaces. The system can also be disabled completely.
Each mode is selected by holding down a toggle button on the left clip-on for approximately one second. This can be done on the fly as long as the throttle is closed. The selected mode is then displayed on the LCD cockpit display. Furthermore the chosen mode selection is stored when the bike is turned off and on again.
(Above) The Kawasaki’s digital instrument panel offers a number of features and is now one of the best set-ups on the market. (Center) The Ninja ZX-10R employs wheelie control that lets you to keep the throttle pinned to the stop when you power wheelie out of a corner. (Below) The Ninja ZX-10R utilizes wheel speed sensors on each wheel to feed information to the traction control and engine management systems.
Considering we’d never turned a wheel at Georgia’s Road Atlanta not to mention the chilly asphalt temperature, we began the test by riding the bike in Level 2 mode. With its sheer number of blind turns and rises Road Atlanta is a very tricky circuit to learn. Still within just a handful of laps it became immediately clear the benefits of the S-KTRC.
There are a number of dips and rises on the track where the bike will power wheelie in second, third and even fourth gear. The TC incorporates a wheelie control functionality that allows you to literally keep the throttle pinned as the front wheel lifts off the ground during a power wheelie. To my surprise, it actually took considerable seat time to get used to this feature as my brain is hard-wired to either: lift off the throttle, dab the rear brake, or tap the clutch lever to get the front wheel back on the pavement. But if you can turn-off your brain and put 100% faith in the electronics it’s simply incredible how well it works with it completely mitigating the chance of the bike looping out and instead putting the front wheel down in a smooth and very natural feeling manner. However, we did notice the system felt herky-jerky in Level 3 as the bike would wheelie then set down and repeat.
After I had put certain segments of the track together I started to get greedy with the throttle when standing the bike up off corners. The rear tire would still spin slightly but it would do so in such a way that you could feel the bike trying to maximize every bit of forward drive. It felt like it would spin, grip, spin, grip as opposed to just spinning excessively when we attempted the same maneuvers with S-KTRC disabled.
But the craziest thing is just how unobtrusive the system is, especially in Level 1. It works its magic so inconspicuously that it’s difficult to tell that it’s even working (there is a segmented bar graph-style TC activation meter on the dash that displays how active it is working but you need to take your eyes off the road to view it). As opposed to other TC systems employed on say the BMW and Ducati, the Kawi’s set-up is far less intrusive when activated and it doesn’t feel like it's restricting acceleration as much.
So will the TC system make the bike totally crash-proof? Not exactly. To test, I dialed in heavy throttle while transitioning from the edge to shoulder portion of the rear Bridgestone BT-003 race tire (learn more about this tire in the Bridgestone Battlax BT003 Tire Comparison) and one time the bike rear end snapped sideways and I popped out of the seat. The only thing that prevented me from crashing was basically luck.
If it doesn’t keep you from crashing what is it good for then? Think of it this way: The TC system takes off the “edge” of aggressive throttle input. It helps smoothen out the load you place on the rear tire during acceleration which in turn reduces wheel spin and maximizes acceleration off a corner. If you’re skilled enough you can certainly accomplish the same goal with your right wrist (Mat Mladin-style) but you’ll never be as consistent as the machine. Hands down this is the best feature of the new 10R and worth every penny of its $13,799 base MSRP.
ENGINE
The new Ninja ZX-10R is a very easy motorcycle to ride around the racetrack.
The previous generation Ninja certainly didn’t lack any top end engine performance with it pumping out in excess of 160 horsepower at the rear tire (see the 2010 Kawasaki ZX-10R Comparison Track article). Although Kawasaki claims maximum power output to have increased it felt comparable to the 2008-2010 Ninja. Kawasaki did note that in stock form the U.S. spec ZX-10Rs are fairly restricted. To prove this they had a “Power Up” bike with a racing exhaust and different ECU and it did feel considerably faster and comparable to BMW’s S1000RR rocket ship. What did feel different however is the way in which the engine generates thrust.
The top-end power hit of yesteryear is gone and the powerband feels flatter than before (good thing). Throttle response continues to be excellent and the engine is very usable and friendly to manipulate at all rpm. We did notice however that it doesn’t pull with the same voracity as you close in on redline with power flattening up slightly. But we did appreciate the soft manner in which the engine hits the rev limiter which felt almost identical to the Z1000 (see the 2010 Kawasaki Z1000 First Ride). The exhaust note continues to be very quiet but there is still a fair amount of air intake howl, much to our pleasure.
The 10R now incorporates an engine power mode selection system similar to Suzuki’s GSX-R line of sportbikes. Three power modes are available ranging from “F” (full power mode), “M” (variable middle power—allows 75% of max power with a less aggressive power curve. Furthermore full power can still be accessed based on the throttle angle rate of change) and “L” (low power—60% of maximum with an even milder power curve). Similar to the S-KTRC system the power mode can be adjusted on the fly (as long as the throttle is closed) by pressing up on the left-hand clip-on toggle button for approximately one second. The selected mode is then displayed right above the S-KTRC setting on the instrument panel with the setting being retained when the bike is restarted.
CHASSIS
(Above) Without having ridden both bikes back-to-back it was difficult to tell if the new 10R is any more agile than the old one. Turn-in did feel more predictable then we remembered however. (Center) The ZX-10R employs a new horizontally-mounted Showa gas-charged shock absorber. (Below) The cockpit layout and riding ergonomics are a big improvement over last year’s bike.
Without riding the bikes back-to-back it was difficult to discern if the new Ninja steers any easier than the old one. Still we wouldn’t exactly term it as “flickable” but it did seem to steer more predictably than before which felt like it could be attributed to its improved mass centralization more than anything. We did notice how much more stable the bike is at high speeds with it headshaking far less than we’ve experience in the past.
We were generally pleased with the performance of last year’s fork and the new Showa BPF continues to provide excellent performance. It does a terrific job of controlling chassis pitch during hard braking, which we experienced entering Road Atlanta’s Turn 10 where you slow down from an indicated speed of 186 mph down to second gear.
Speaking of braking the Ninja continues to offer a very powerful braking set-up. Outright stopping force is incredible and the brakes didn’t fade at all at our pace. Initial bite is rather low which helps make the brakes easier to use for a novice rider but gradually ramps up as lever force is increased. Additionally the Ninja now offers an anti-lock braking system available as a $1000 option. The system only adds six pounds to the weight of the motorcycle; however it cannot be disabled like say the system employed on the BMW S1000RR. The bikes we rode were not outfitted with the system so look for a review in the future.
Even more impressive than the fork perhaps was the new horizontally-mounted Showa shock absorber. Overall the rear end of the bike seemed to squat less during hard acceleration and there was a high-level of feel during cornering. When you combine that along with the fantastic grip from the Bridgestone BT-003 race tire and phenomenal performance of the traction control system, the package facilitates strong drives off corners. Damping force also remained consistent throughout our 20-minute riding sessions.
ERGONOMICS
Next to the performance of the traction control system the revised cockpit and riding ergonomics is another area where the new 10R shines. Part of the reason why it feels much less top heavy than before is the 0.7 inch reduction in seat height. The profile of the fuel tank is also vastly improved with it feeling much more compact than before. We also liked
The traction control system employed on the new 10R is the best system we’ve ever tested on a production motorcycle.
FINAL THOUGHTS
Although we weren’t blown away by the added performance of the engine or chassis as compared to last year’s bike the electronics package on the new 10R is out of this world. Not only does it make the bike easier and safer to ride it allows you to better explore the astronomically high-performance that a modern day Superbike serves up. And to think that you can get a taste of a similar type of traction control and engine management technology that MotoGP bikes were using just a few years ago for a list price of $13,799 is absolutely mind boggling. Kudos to Kawasaki for continuing to evolve the realm of sportbikes with its easy-to-use and gimmick-free traction control system.
