The 2025 Kawasaki Ninja ZX-4RR in the legendary Lime Green and Ebony KRT colours is a revolutionary machine that brings true supersport performance back to the 400cc class. This brand-new, zero-mile motorcycle arrives at On Yer Bike in showroom condition, complete with a factory-fitted DataTag system and an immobiliser for superior security. Unlike any other modern middleweight, the ZX-4RR is powered by a high-revving 399cc inline-four engine that produces a staggering 77 hp (rising to 80 hp with Ram Air). With a redline exceeding 15,000 rpm, this 77 hp screamer delivers an intoxicating exhaust note and a level of mechanical engagement that only a four-cylinder Kawasaki can provide.
The "RR" suffix marks this as the range-topping variant, equipped with high-spec track-ready hardware. It features Showa SFF-BP front forks with adjustable preload and a Showa BFRC-lite rear shock—the same technology used on the flagship Ninja ZX-10R—ensuring world-class handling and feedback. Braking is equally impressive, with dual 290mm semi-floating front discs and radial-mount monobloc calipers providing massive, predictable stopping power. Despite its aggressive performance, the lightweight trellis frame and slim proportions make this 77 hp machine remarkably nimble and accessible for both road and track use.
The 2025 ZX-4RR is packed with rider-focused technology, including a dual-direction Kawasaki Quick Shifter (KQS) for seamless clutchless shifts, Kawasaki TRaction Control (KTRC), and multiple riding modes (Sport, Road, Rain, and Rider). The 4.3" full-colour TFT display offers "Circuit Mode" for lap timing and features Smartphone Connectivity via the Rideology app. As an official Kawasaki dealer, On Yer Bike provides this bike with a 4-year manufacturer warranty.
