aprilia is an old bike n the parts r ex, thats y alot of pple
cant be bothered to fix n then make alot of noise sayin it
problematic..
if it is problematic, who make it problematic...
up to the end, its up to the owner to take care of his RS
i seen problematic TZR, SP, TZM....also
but then it is all up to the owner whether they take it...
the RS is a bery sensitive bike tat needs regular care...
one last thing, yes, the parts r ex, becoz they r italian racing
parts, not parts from thai or msia
