Öhlins Rear Shock for Kawasaki Ninja ZX-4R (23-25), ZXR 400 (24-25) KA 401

The Öhlins rear shock absorber for the Kawasaki Ninja ZX-4R and ZXR 400 combines stability and comfort with scope to fine-tune your bike’s suspension. Its STX 46 monotube technology is aimed at middleweight sports bikes, balancing sporty riding with everyday use.

The external piggyback reservoir helps manage heat and maintain stable pressure during prolonged, demanding riding. A high-pressure nitrogen charge helps prevent cavitation and keeps the damping response consistent.

• Damping control: independent compression and rebound adjustment lets you tailor the response to riding conditions.
• 46 mm piston: provides precise control of hydraulic fluid flow.
• Accessible preload: a hydraulic hose and external adjuster allow changes to suit rider and luggage weight without additional tools.
• Geometry adjustment: adjustable shock length allows you to alter the bike’s geometry to suit your requirements.
• Construction: CNC-machined components with hard anodising provide durability and precision.
• Sensitivity: a low-friction shaft and seal design reduces energy losses.
• Servicing: fully serviceable and repairable by a specialist technical service.

Installation by a qualified suspension specialist is recommended.
