Push the stud's rivets completely through the seat cover until the prongs protrude out from the inside of the seat cover. Bend the prongs toward each other with a pair of needle-nose pliers to secure the stub in place. Push the prongs of the next stud into the seat cover near the previous stud. Remove the stud and cut holes for the prongs. Push the stud into place and bend its prongs in with a pair of needle-nose pliers. Repeat until you have studded to the seat to your liking. Double check the stud prongs on the inside of the seat cover. Make sure that all of the prongs have been bent completely and that the studs are held firmly in place. Lay the seat cover over your motorcycle's seat pan, then flip the entire seat upside down.
