Not really sure bought the sintered pads for the America no problems but the America went through the first set of rears about 3000 miles the new set are still good after 5000 miles. Possibly the first 300 miles is the time it took me to get used to the bike. Not sure but try this mob on flea bay and compare prices not that great a difference. even counting postage
