Does this relay incorporate an over-voltage suppression diode ?

Sorry, I don’t know, but it works well on 12 volts.

Would this work in a 2011 Harley sportster xl custom?

Hi, yes it is a 12 volt relay and should work well.

It is somewhat unclear, is this a normally close relay?

This relay is a changeover relay and can be used as both normally open (no), and normally closed (nc) depending on how you connect it up. However being used as a normally closed relay will result in a reduction in current switching ability depending on what sort of load is being switched

Buen producto

Relé a buen precio que realiza correctamente su función. Recomiendo dar unas vueltas con cinta aislante en la zona que se une la carcasa negra con su base donde están las conexiones, para una mejor protección contra la humedad.
