Piston Size Is 53.97mm This Is The Only Size This Piston Comes In Please Note This Piston Has The Ring Peg In The Centre Of The Piston As Shown In The Image Below. This Means That The End Of The Piston Rings Run Across The Inlet Port, This Is Perfectly Normal Practice, KTM, TM And Honda RS125 Race Bike All Have A Centre Pegged Piston Running Over A Open Port, However This Does Reduce The Service Life Of Both Piston And The Piston Ring.
