Kawasaki Ninja ZX-4RR Parts & Accessories ('24-'26) at HardRacing

The Kawasaki Ninja ZX-4RR has taken the sport bike world by storm — a rev-happy 399cc inline-four engine with a 16,000 RPM redline, race-derived chassis, and a price point that makes it accessible to a new generation of performance riders. HardRacing is building out a comprehensive catalog of ZX-4RR parts, performance upgrades, and accessories for the 2024, 2025, and 2026 model years.

Top upgrades for the ZX-4RR include full exhaust systems and slip-on mufflers that unleash the four-cylinder's extraordinary high-rpm soundtrack, brake line upgrades for improved feel and fade resistance, fender eliminators for a cleaner tail section, and frame sliders and crash protection for track day peace of mind. We also stock ECU flash and fuel management solutions compatible with the ZX-4RR's sophisticated electronics.
