Hey guys, new to the HD family, loving my 2019 street bob. However, I am having trouble finding out what size Torx bits I need in order to remove the support bracket to install a sissy bar. Any help would be much appreciated.

 

I believe it's T45.

 

I usually bring my set to the bike and try them out to find the right one (always trying the next size up as it’s easy to mistake a smaller size and strip it). If you’re asking his because you want to go buy the one bit for the job, I recommend you just buy a full set. You'll need them if you’re going to be working on your bike in the future.

Before I bought a set of Blue Point’s I used Neiko bits from Amazon. Plenty good quality and $15 for the set...

 

You will need a T27 for a lot of the FXBB screws. Not all kits have this so make sure you specifically look for one that includes it

 

This is a very good quality set (for offshore manufacturing), has all you’ll likely ever need.
