The Akrapovic Racing Line is a complete exhaust system with a carbon fibre muffler for the 2021-2025 Kawasaki Ninja ZX-10R and ZX-10RR.
Kawasaki's 2021 revision brought new bodywork, new aerodynamics and a Euro 5 exhaust that is noticeably larger than what it replaced. The catalyst sits in the mid-section, which is why a slip-on gets you sound but not much else on this generation — the restriction is upstream of the can.
Racing Line replaces the whole path. It is the step between the road-legal Slip-On Line and the all-titanium Evolution Line: a complete system, built for performance rather than for type approval, at a price that reflects using the right material in each place rather than titanium everywhere.
The ZX-10RR in particular deserves it — Kawasaki built that bike specifically as a homologation special for World Superbike, and its engine responds to being allowed to breathe.
Fits the 2021-2025 Kawasaki Ninja ZX-10R and ZX-10RR. The 2016-2020 generation takes a different system — check your model year before ordering.
Racing Line systems are built for performance rather than type approval. Confirm the emissions and sound rules where you ride, and expect to need an ECU flash for correct fuelling.
