These cast aluminium GB plates have been made smaller than the car ones currently available elsewhere so they are ideal for motorcycles. They measure approximately 120mm long and 63mm tall with 45mm tall letters. The back of the plate has four dimples in it to aid in lining up the drill so you can drill your own plate to have the fixing screws at either 12 and 6 o'clock or at 9 and 3 o'clock. 
 
Made from LM6 aluminium they have a high resistance to corrosion and polish up very nicely! They are stove enamelled gloss black so are hard wearing and look very neat on any vintage or classic bike.
