i use one on my mk 7 250 , i think it,s from mk 5 ( i think mk 5 is the first after the boat tail,s ) i know they are a little heavy but braking performance far outweighs the weight disadvantage over the spray on chrome drums that look the same , had i not have one already i would offer a swap for some ty175 pegs and stand and plates , i think too heavy for trials(mabey not ?) and won,t fit the frontera,s
