The Ninja ZX-10R and ZX-10RR superbikes receive numerous upgrades, making them more fun to ride, more efficient, and less-polluting.
The Japanese brand didn’t rest on its laurels, though. It just released upgrades for the Ninja ZX-10R and the ZX-10RR with improved performance but also reduced emissions. The WorldSBK winter test just took place in Jerez, and Kawasaki introduced the production models just in time.
Ninja ZX-10R – Superbike for the Street
The bikes have received a significant upgrade in terms of design, engine, and suspension. The 2021 Ninja ZX-10R now comes with electronically-accentuated valves, new gear ratios, an air-cooled oil-cooler, and a Euro 5-compliant exhaust system. Furthermore, the new chassis now provides better cornering, as the framework runs straight from the handlebar to the rear axle.
Outside, the Ninja ZX-10R features a new front fairing with LED lights, making it legal to drive on the streets. The front also looks more aerodynamic and features integrated winglets that improve downforce by 17%.
Kawasaki also altered the riding position to make the rider feel as comfortable as possible. Meanwhile, a taller front visor gives better wind protection.
There is a new 4.3-inch touchscreen to the front console as well. And surprisingly, even though the ZX-10R is meant for the street, the screen features all the gauges necessary for a track bike, including the digital speedometer, tachometer, odometer, gear position indicator, fuel gauge, etc. Furthermore, it supports Bluetooth connectivity to access the Rideology app, which shows instrumentation info, riding log, and tuning. There is also a new Electronic cruise control system with three standard and four customizable riding modes.
Kawasaki also introduced new brake pads and a repositioned rear brake reservoir on the 2021 Ninja ZX-10R. The suspension also gained upgrades, this time with the help of KRT, who transferred weight to the front, improving handling and performance.
Also, the Showa balanced free fork now has a lower spring rate, tougher compression damping, and softer. As usual, Kawasaki employed track-ready features such as launch control, quick shifter, and traction control.
Ninja ZX-10RR is the Track-Focused Version
Closer to the WorldSBK edition, the 2021 Ninja ZX-10RR takes the motorcycle to the next level. The track-ready model features more aggressive camshafts with new intake and exhaust valve springs. Also, the connecting rods and pistons are now Titanium for weight reduction and performance gains.
The 2021 Ninja ZX-10RR also comes with improved airflow, eliminating intake funnels. Moreover, the wheels are Marchesini forged, and the Pirelli Diablo Supercose SP tires increase track performance.
The ZX-10R starts at $16,399 for the Metallic Spark Black/Metallic Matte Carbon Gray color wave and $16,699 for the KRT editions that come in Lime Green. The ABS version will cost $1,000 more.
Meanwhile, the more aggressive ZX-10RR starts at $28,999 and is only available in the traditional Kawasaki Lime green color.
