The Akrapovic Slip-On Line is a bolt-on carbon fibre muffler for the 2020-2024 Kawasaki Ninja 1000SX and the 2025 Ninja 1100SX, including the SE.
The 1000SX is a sport tourer built on superbike underpinnings, and the way people actually use it — luggage on, long days, occasionally very fast — shapes what matters here. The muffler is compatible with Kawasaki's side cases, which rules out a good many aftermarket options for this bike.
The measured gains are honest rather than dramatic: +0.4 kW at 9,600 rpm and +2.3 Nm at 1,860 rpm. Note where that torque lands — just off idle, which on a heavy sport tourer pulling away with a pillion is where you use it.
Fits the 2020-2024 Kawasaki Ninja 1000SX and the 2025 Ninja 1100SX and 1100SX SE. Akrapovič also builds this muffler in titanium (S-K10SO32-HRT) for the same machines.
