I think the diameter of the studs is too small. If they had used M8 studs instead of M6 they would have been a lot stronger. Also using the open ended nuts was a bad idea because all the muck from road clogs up the threads. I think it's nearly always the center two studs behind the wheel that snap. Even if you crack the nut free and get a few turns out of it they can still shear because they bind up from dirt and rust on threads because the nut is open. Also whatever steel they made the studs and the whole exhaust from wasn't good enough. It rusts out too easily. I know the Fazer was a budget commuter when it was sold but Yamaha really cheaped out on the exhaust system
