DescriptionThe whole story▼
When chain lube, grit and road spray are eating into your Ninja 400's swingarm and undertail at every track session or wet commute, the stock mudguard simply isn't enough. Puig's rear fender extension clamps directly over the original fender to deliver serious added splash protection, finished in matte black ABS that blends with the Ninja's factory bodywork without a millimetre of visual bulk.
Key Features
- Track-proven ABS construction — acrylonitrile butadiene styrene absorbs impacts from stones, debris and kerb strikes that would crack lesser plastics at pace
- Genuine rear tyre hugger coverage extends the OEM mudguard rearward, shielding the swingarm, chain, shock and undertail from chain splash and road spray
- Matte black factory-matched finish preserves the Ninja 400's clean aesthetic on and off the circuit
- Purpose-engineered bracket geometry mounts flush over the original rear mudguard for a zero-gap fit
- Supplied with all fixing screws by Puig — no hunting for hardware before your next track day
- Lightweight at just 376 g, adding meaningful protection without measurable handling penalty
Performance on Track and Road
The Kawasaki Ninja 400 is as at home on a track day as it is on a Sunday morning B-road blast, and Puig has engineered this rear fender extension with both environments in mind. At circuit speeds, the undertail fender acts as an anti-splash guard, keeping abrasive grit away from the chain, rear shock and suspension linkages where wear accumulates fastest. On wet roads, it functions as a comprehensive rear splash guard, preventing the chain oil and tyre water spray that accelerates corrosion on exposed swingarm components. The matte ABS surface is UV-stable and resistant to chain lubricant, brake fluid splash and cleaning chemicals — meaning it stays looking sharp through a full season without fading or cracking.
Installation
The rear mudguard extension fits directly over the Ninja 400's original rear mudguard and is secured using the screws Puig includes in the box. Installation requires drilling holes in the original fender — a straightforward task, and Puig provides a dedicated assembly guide available to download from their official website, with step-by-step tips to make the process quick and accurate. No specialist tools beyond a drill are needed.
