There's nothing wrong with the Metz, which Triumph had purpose built by the mfr., specifically for our monsters, 10 years ago and still equip R3s with today. The "problem" is either with the type of roads some folks ride on (the type that eat tires up very quickly) or, more commonly, with some folks riding styles (barhopping, burnout freaks) often combined with a lack of proper tire maintainance or a bad setup (altered geometry).
