The new Kawasaki ZX-10R for 2016

0 Posted by - 08/10/2015 - Motorcycles

Shown below is what a maximum benefit for Kawasaki looks like when you have guy’s like Jonathan Rea and Tom Sykes around to do your fieldwork. Thanks to their experience and feedback, the Ninja ZX-10R comes closer to a WorldSBK racer than ever. While the new bike may look outwardly similar to the current model, the truth is that barely a nut or bolt has been left untouched. The raft of changes to the engine, chassis, suspension, fairing, electronics, brakes and exhaust is extensive, and even parts that look identical have had the magic R&D wand waved over them.

All of the changes were aimed at keeping the bombastic power of the 2011 bike, while boosting low to mid-range power to help with acceleration out of corners. With a completely new cylinderhead and crank – that has lost 20% of its weight – Kawasaki claim the new engine’s reduction in inertia allows it to spin-up much faster. The lighter crank has several other side-effects, too. Not only does it benefit acceleration, but with less sored energy in the crank, it can be decelerated faster, while cornering forces are reducing thanks to the reduction in the gyroscopic effect of the rotating mass. The new cylinderhead’s intake ports are straighter and wider to allow a greater volume of fuel/air mixture to flow more easily into the combustion chamber and to contribute to power production. The exhaust ports are also straighter and wider to allow the chamber to purge more efficiently. Both intake and exhaust ports are also polished to improve gas flow, while the larger diameter intake and exhaust valves are now made from titanium to reduce mass. Larger coolant passageways also help keep the extra heat generated under control. The engine has revised cam profiles to optimise valve overlap for a strong balance of torque and high-endpower, while their chromoly construction further aids the weight reduction. The pistons are shorter and lighter with revised crowns while thicker cylinder walls and a rerouted cooling system have been proven improvements from the firms racing developments. And all of this has been done while still passing the strict Euro4 regulations for noise and emissions.

The airbox is now two litres larger, at 10litres, giving the engine a large volume of air to draw from all helped by a ram-air intake which has been moved further forward for greater efficiency, and an air filter with a larger surface area and higher flow rate. All this conspires to deliver a claimed 207bhp (with ram air) at 13,000rpm, and 84ftlb torque at 11,500rpm. Shedding weight was a priority, so the new bike uses titanium headers identical in size to the race bike. Kawasaki say this means trackday addicts and racers will only have to replace part of the exhaust to get a fully track-focussed system. There are now three catalysers to help the bike pass stringent Euro4 emissions and noise tests, while the silencer is also now titanium – not stainless steel.

The new front suspension has been jointly developed by the WSB team and Showa, with their Balance Free Front Fork making its mass-production debut on the new ZX-10R. At the rear there’s the firm’s Balance Free Rear Cushion (BFRC) shock. The 43mm fork is said to offer increased ride comfort, braking stability, improved front-end feel, with each leg being independently adjustable for compression and rebound damping. Each leg boasts a separate compressed nitrogen gas canister at the fork bottom with damping force generated separately to the main tube in a different chamber. This allows the whole surface of the main piston to act as a pump, pushing oil towards the valves and keeping pressure more constant. While the front calipers are now top-of-the-range Brembo M50 cast aluminium monoblocs, radially-mounted and gripping 330mm twin discs via braided steel hoses. The discs are 20mm wider in diameter than the outgoing bike and they have grooves around the outer edge to increase their surface area and therefore cooling. At the rear a 220mm single disc is gripped by a single piston caliper and also gets steel braided brake lines. At both ends the once fashionable petal discs have succumbed to good old-fashioned round discs.

The new bike also gets the latest batch of control systems, all based around the Bosch Inertial Measurement Unit (IMU) which operates through five measured axes plus a calculated programme which allows the bike to know what is going on in terms of lean angle, pitch and yaw, acceleration and braking. Kawasaki have emptied a bucket of acronyms over this bike and that includes: new Sport-Kawasaki TRaction Control (S-KTRC), Kawasaki Launch Control Mode (KLCM), Kawasaki Intelligent anti-lock Brake System (KIBS), Kawasaki Quick Shifter (KQS), Kawasaki Engine Brake Control (KEBC). The bike also has an Ohlins electronic steering damper and a new power mode selection. A larger top fairing was requested by the WSB team to help improve high-speed stability and aerodynamic flow. Increased wind protection is claimed to help racers change position more easily under braking turns because the air is less turbulent. The windscreen is now fully supported by the fairing and shouldn’t vibrate as much as the current bike’s at high speed. Intakes at the side of the windscreen reduce negative air pressure in the cockpit to stabilise airflow and reduce helmet buffeting. A new front mudguard gets a stepped design helping to direct air to the radiator to increase cooling.
