  • Bad fitment & no refund
This part didn’t fit and the seller/Amazon is not letting me return. What a waste of money and time. This is still brand new but doesn’t work, let me get my money back…

  • Works, had to modify
Works as it should on a 2017 ssr 70cc. Had to cut off spacer from original bracket. Lines up perfect on rotor. Also pre bled.
