Give the Monster 821's minimalist tail a purposeful, factory-look finish while shielding it from road grime. This Puig rear fender extension bolts beneath the original fender, extending its coverage into a proper rear tyre hugger without disrupting the naked bike's clean silhouette.
Key Features
- Extends the original fender for genuine rear splash guard protection
- Matt black ABS finish blends seamlessly with the factory bodywork
- Doubles as a chain splash guard, keeping muck off the swingarm and drivetrain
- Fitting kit includes Puig-supplied screws
- Lightweight construction at just 276 g adds negligible mass to the tail
Design and Build Quality
Moulded in acrylonitrile butadiene styrene (ABS), this rear mudguard extension is engineered to resist stone chips, road spray and general wear better than the stock fender alone. The matt black paint finish is chosen specifically to disappear into the Monster's existing rear end, so it reads as an OEM upgrade rather than a bolt-on accessory — heritage styling that respects Ducati's design language rather than fighting it.
Fitting Notes
The extension mounts directly over the original fender and is secured with the screws Puig supplies in the kit. Fitting does require drilling holes into the original fender, so this is a permanent modification best suited to owners committed to the upgrade. Puig also provides a downloadable fitting guide with practical tips to make the installation straightforward.
Fitment & Compatibility
Designed specifically for the Ducati Monster 821, model years 2015, 2016, 2017, 2018, 2019 and 2020.
