Does anyone know what the rear axle diameter is on a 2013 Street Bob? I'm looking to order a side mount vertical bracket for my license plate and not sure if I need a 3/4" or 1" hole. Thanks in advance

 

Pretty sure it's 25mm

 

yeah so 25mm= .984 inch...so 1 " will work in your application.

 

Only if he is changing out his bearings and spacers also. The bearings and spacers are all made for the 25mm axle, a 1" axle is 25.4mm.

 

Yeah so a 1" license plate bracket that slides over the 25mm axle will fit fine, at least that's what it sounds like he's asking about.
