Ex Demo Kawasaki NINJA ZX-4RR

This is the NINJA ZX-4RR model variant of the Kawasaki range, available to buy at On Yer Bike.

Features a high-revving inline-four supersport engine, factory bi-directional quickshifter, fully adjustable Showa Balance Free Rear Cushion (BFRC) lite monoshock, and selectable integrated riding modes. This thrilling 2026 Kawasaki Ninja ZX-4RR is presented in iconic Lime Green and Ebony livery, having covered just 340 miles from new as an official ex-demonstrator under 1 owner. Maintained in very good condition throughout, this high-specification lightweight race-replica comes complete with balance of manufacturer warranty, original V5 docs, and 2 keys. Engineered for track day enthusiasts, sports bike purists, and demanding road riders seeking real screaming four-cylinder performance in a lightweight package, this benchmark supersport offers razor-sharp agility and thrilling high-RPM dynamics.


At the heart of this compact supersport machine is a screaming 399cc liquid-cooled DOHC 16-valve inline-four engine producing 77 hp, revving to a dizzying 15,000 rpm redline and paired with a 6-speed transmission featuring Kawasaki Quick Shifter (KQS) for seamless clutchless up and downshifts. The race-inspired trellis chassis incorporates 37mm Showa SFF-BP inverted front forks with adjustable preload, a Showa BFRC lite rear shock, and dual 290mm semi-floating front brake discs clamped by radial-mount 4-piston monobloc calipers for exceptional stopping power. Advanced electronic rider aids include 3-mode Kawasaki Traction Control (KTRC), selectable power modes, full-colour 4.3-inch TFT display with Rideology smartphone connectivity, factory immobiliser, full LED lighting, original documentation, and official Kawasaki dealer representation.
