Built around a precision-machined 35 mm body with a fully separated internal nitrogen reservoir, this shock absorber is constructed to standards that go far beyond anything the Ninja 400 leaves the factory with — delivering consistent, fade-free damping on every road or track session.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInternal nitrogen (N2) reservoir separates gas from damping oil, preventing aeration and maintaining consistent performance throughout extended riding sessions\u003c\/li\u003e\n\u003cli\u003e16-click rebound damping adjustment allows precise fine-tuning of the shock's return speed to suit riding style and road surface\u003c\/li\u003e\n\u003cli\u003eAdjustable spring preload lets you dial in the correct ride height and sag for your exact weight and load\u003c\/li\u003e\n\u003cli\u003eLength adjustment range of -4 mm \/ +6 mm from the 320 mm standard length gives you meaningful geometry control without custom fabrication\u003c\/li\u003e\n\u003cli\u003eMultiple spring rate options available (46-180 series) so you can match the unit to your specific weight range and riding demands\u003c\/li\u003e\n\u003cli\u003e12 bar nitrogen charge and a 14 mm piston rod ensure structural rigidity and long service life under repeated compression cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Premium Materials\u003c\/h2\u003e\u003cp\u003eK-Tech manufactures the RAZOR-R LITE to the same exacting tolerances as their higher-end race units. The 35 mm RCU housing is machined from high-grade aluminium, keeping unsprung weight to a minimum while providing the structural integrity needed to handle the stresses of spirited road riding and track days alike. The 14 mm piston rod is precision-ground to resist side-loading, and the internal sealing package is designed for long service intervals without performance degradation.\u003c\/p\u003e\u003cp\u003eThe eye-type upper and lower mounting hardware — 30 mm wide with a 10 mm bolt diameter at the top, 40.4 mm wide with a 10 mm bolt diameter at the bottom — is a direct, bolt-on replacement for the Ninja 400 OEM unit, requiring no frame modification. The 65 mm stroke and 100 N spring rate have been validated specifically for the Ninja 400 chassis, ensuring the geometry and progressivity suit the bike's architecture rather than being a generic off-the-shelf fitment.\u003c\/p\u003e\u003ch2\u003eOn the Road and on Track\u003c\/h2\u003e\u003cp\u003eRiders upgrading from the standard Kawasaki shock will notice an immediate improvement in mid-corner composure, braking stability and overall rear-end confidence. The ability to adjust preload, rebound and ride height independently means the RAZOR-R LITE remains relevant as your riding evolves — from commuting and weekend touring to track days and club racing. The 8 mm preload adjustment range and 3 mm RCU travel give meaningful scope for setup changes without specialist tooling, though K-Tech recommends installation and initial setup be carried out by an authorised K-Tech Service Centre to ensure full performance and safety.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis shock absorber is a direct OEM replacement fitment for the following motorcycles:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKawasaki Ninja 400 (2018–2023)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring series\u003c\/td\u003e\n\u003ctd\u003e46-180\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall length\u003c\/td\u003e\n\u003ctd\u003e320.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOil\/air gap\u003c\/td\u003e\n\u003ctd\u003e20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength tolerance\u003c\/td\u003e\n\u003ctd\u003e-4 mm \/ +6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e65.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring rate\u003c\/td\u003e\n\u003ctd\u003e100.00 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas pressure\u003c\/td\u003e\n\u003ctd\u003e12.00 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpper mount\u003c\/td\u003e\n\u003ctd\u003eEye, 30.00 mm width, 10.00 mm bolt diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower mount\u003c\/td\u003e\n\u003ctd\u003eEye, 40.40 mm width, 10.00 mm bolt diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRebound clicks\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePreload\u003c\/td\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCU adjustment range\u003c\/td\u003e\n\u003ctd\u003e3.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCU body diameter\u003c\/td\u003e\n\u003ctd\u003e35.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiston rod diameter\u003c\/td\u003e\n\u003ctd\u003e14.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eInstallation must be carried out by an authorised K-Tech Service Centre.
