AEM Factory KTM Super Duke Sprocket Flange “K-SEI”


The AEM Factory’s sprocket flange “K-SEI” represents a premium finishing touch for your KTM motorcycle.

We are pleased to announce that we have a brand new sprocket flange available for the KTM Super Duke 1290-1390. This design is inspired by the distinctive aesthetic we use for Ducati’s.

As usual, our goal is to achieve the best possible mass reduction while improving the rigidity and resistance of the OEM counterpart.


We highly recommend ALWAYS using a medium-strength thread locker such as Loctite Blue 242 (or similar products) on EACH thread.


Available in 4 stunning colours.


Fits KTM models:

Super Duke 1290 GT 2016+

Super Duke 1290 R 2017+

Super Duke 1290 R Evo 2022+

Super Duke 1290 RR 2021+

Super Duke 1390 R Evo 2024+
