DescriptionThe whole story▼
Push your Monster 821 Dark harder without worrying about roost, road spray or track debris fouling your rear shock and chain. This Puig rear fender extension bolts straight onto the original mudguard, extending its coverage exactly where fast riding throws the most muck and grit.
Key Features
- Acts as a rear tyre hugger, tightening up splash protection behind the wheel
- Doubles as a chain splash guard, keeping road grime off the drivetrain during hard riding
- Moulded in tough ABS for genuine impact resistance, not just cosmetic plastic
- Finished in matt black to blend seamlessly with the factory fender
- Fits directly over the OE rear fender for a clean, factory-style undertail fender look
- Puig-supplied screws included for a secure, rattle-free fit
Built for Performance Riding
Whether you're pushing on through wet corners or hustling the Monster 821 Dark down a damp back road, this rear mudguard extension keeps the rear end cleaner and the suspension components better shielded from abrasive spray. It's the kind of small upgrade that pays off when you're riding with intent rather than cruising.
Fitment Notes
Installation is straightforward but requires drilling into the original fender to mount the extension securely. Puig provides a downloadable fitting guide with tips to make the job easier, so you can get it done properly the first time and get back on the bike.
