Developed in conjunction with the World Superbike Kawasaki Racing Team, the new Ninja ZX-10R and ZX-10RR has been refined with a further focus on performance and handling. The biggest upgrade comes in the form of an innovative new aerodynamic package that creates up to 17% more downforce than the previous model thanks to incorporated winglets.
 
The chassis has also been updated, with a new 1mm lower swingarm pivot point, 2mm greater front fork offset and an 8mm increase in swingarm length. Spring rates have changed too, with the front now softer and the rear harder, while a wider fork clamping area for the lower triple-clamp revises the rigidity balance for the outer fork tubes.
 
The engine of the Ninja ZX-10R and RR continues to utilise finger follower valve actuation, which helps to increase power and efficiency while reducing valve train weight. Gear ratios are refined with 1st, 2nd and 3rd lower to make the best use of the Ninja’s prodigious power, which is further enhanced by a new inlet port design. The 2021 machine has also been engineered to meet Euro 5 regulations.
