There are spindle bobbins and there are spindle bobbins. When i bought my Ducati in 01 i bought some bobbins that were basically a length of M8 all thread with a solid plastic bobbin on each end that didn’t rotate when the nuts on the all thread were fully tightened.
Whereas the Evotech ones i have on my Striple will allow the black plastic bung to rotate even when the nuts on each end of the all thread are fully tightened. The logic behind this is that if the bobbins are fixed they will be quickly ground away when in contact with the blacktop whereas if they are allowed to rotate their degradation will be much reduced thus providing protection for a longer duration.
Whilst they are not listed on the Evotech website for your machine i would give them a call. But before you do you will need to gather some details from your machine such as axle length, diameter of hole through it and what each end of the axel looks like, with dims if it’s other than just an external thread. After all they are just a threaded rod with a bobbin on each end and they make them for so many manufacturers, each with numerous bikes listed i would be most surprised if they couldn’t come up with a pair to fit your machine.
Below you can see them fitted to my Striple which i have since fitted their tail tidy.
