Grade AA – first-class repair Product description
Whoever maintains and works on their scooter themselves should make sure a supply of suitable fastenings, gaskets, etc. are available in your workshop all times. What can be more annoying then being in the middle of a complete engine rebuild or similar to be stopped in your tracks by the lack of any particular nut or bolt?
