Hi Herbalrick, welcome to the TC. Looks like you've got a nice tidy one there! even got the rear seat cover which is rare. Dropping the bars is easy enough, just check your clearance on the tank! but I would try it standard first....how good is your back?
Not that much goes wrong with XBR's generally and spares are mostly easy. Worth checking the back brake doesn't 'pulse' when applied at low speed, this could be an oval drum lining which can be a problem to sort.
