A hard to find genuine and original Rotax engine cylinder barrel for the RS 125 and AF1 bikes, it has GILARDONI 2, 220S, ROTAX 223997 stamped on the intake sides of it. all threads are good, but it will need a re plate overhaul due to a vertical line on the bore so sold for overhaul, If you want a genuine barrel in very good outside condition at a very fair price that needs the bore re plating then this is a bargain, check out the new prices for one even if you can find one for sale !
