Brand new Mustard Bikes tail tidy for the 2018 onwards KTM Duke 790 and 2020 onwards Duke 890.

Our fender eliminator will refine your bikes sleek and purposeful look. The tail tidy mounts your numberplate up close to the undertail removing and replacing the unsightly stock bracket and tail light.

This part has been CNC cut from lightweight 3mm aluminium for maximum strength combined with minimum weight and finished in a tough satin black powdercoat for a durable finish. 

The fender eliminator mounts right where the old fender was mounted. No modifications are needed to get it to fit because it's been designed to use the original mounting points of the OEM fender. All the installation hardware is supplied, and a full step by step video guide is available to make your installation a breeze

An E-marked and ADR compliant brake light is integrated into the design to replace the large stock item and it comes with the OEM connector to make it plug and play. Indicator mount design supports any width plate.


USA / CANADA CUSTOMERS: The indicators supplied with the 790/890 Duke in the US/Canada will not withstand the exhaust heat when used with this product due to the larger size of the indicators compared to the LED indicators this product was designed for. An alternative indicator must be used, taking this issue, along with local and state laws, into account. Please ensure this product is suitable to your needs prior to purchase.


All Mustard Bikes fender eliminators are designed and manufactured in Australia.

Tail Tidy KTM 2023 890 Duke R

9 June 2023
I have previously purchased tail tidys for my last five bikes from Mustard. Latest being for a KTM 2023 890R. Like the previous purchases, I had no difficulty fitting it. The video instructions were spot on. The quality of the manufacture is excellent. I have fitted an Akrapovic slip-on exhaust and there is no clearance issues with the blinkers.
