The Ninja 400 is a small sportbike built to be revved, and this system finds its gain exactly where the engine wants to be — not in a mid-range that a 400 barely has.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2.78 kg against the standard 4.08 kg: 1.3 kg and 31.9 per cent less\u003c\/li\u003e\n\u003cli\u003e1.5 PS more at 10,300 rpm, peak output rising from 44.3 to 45.8 PS\u003c\/li\u003e\n\u003cli\u003e0.8 Nm more at 8,300 rpm\u003c\/li\u003e\n\u003cli\u003eTitanium muffler outer sleeve\u003c\/li\u003e\n\u003cli\u003eTwenty minutes to fit, removable noise insert supplied\u003c\/li\u003e\n\u003cli\u003eFits the faired Ninja 400 and the naked Z400\u003c\/li\u003e\n\u003cli\u003eEC and ECE type approved, A2 restriction untouched\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eA Bike Where 1.3 Kilograms Is a Real Share\u003c\/h2\u003e\n\u003cp\u003eThe Ninja 400 weighs 168 kg ready to ride. Removing 1.3 kg is close to one per cent of the whole motorcycle, taken from the highest and furthest-back point, and on a machine this light a rider notices it in slow-speed handling and in how quickly the bike falls into a corner.\u003c\/p\u003e\n\u003cp\u003eThat is also why the standard silencer is heavy: Kawasaki built the Ninja 400 to a price, and the exhaust is where the money was not spent. It is the same pattern seen on every affordable motorcycle in this catalogue.\u003c\/p\u003e\n\u003ch2\u003eA2 and the Certificate\u003c\/h2\u003e\n\u003cp\u003eThe Ninja 400 and Z400 sit inside the A2 licence class, and most of them are ridden by people on a restricted licence. A non-approved exhaust on such a machine puts the restriction certificate and the insurance cover in question — a disproportionate risk for a part at this price.\u003c\/p\u003e\n\u003cp\u003eThis one carries EC and ECE type approval and changes neither. The removable noise insert lets the sound be kept close to standard for an inspection.\u003c\/p\u003e\n\u003ch2\u003eNinja 400 and Z400\u003c\/h2\u003e\n\u003cp\u003eKawasaki sells the same 399 cc parallel twin in two bodies: the faired Ninja 400 and the naked Z400 with a wide handlebar and an upright seat. The frame and the exhaust mounting are shared, so one silencer serves both.\u003c\/p\u003e\n\u003ch2\u003eWhat Stays Standard\u003c\/h2\u003e\n\u003cp\u003eThe header, the catalytic converter and the engine management are untouched, no remapping is required, and the original silencer bolts straight back on. On a first big bike that will be sold on within a few years, having the standard parts in the box is worth real money.\u003c\/p\u003e\n\u003cp\u003eInstallation is twenty minutes. The Ninja's lower fairing does not have to come off — the silencer is reachable from below with the bike on its side stand.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-K4SO7-HRT covers the Kawasaki Ninja 400 from model year 2018 through 2024 and the Z400 from 2019 through 2024.
