Clutch backplate for pre-Verto clutch, for replacing ones with badly scored friction surface. Standard material, but lighter at 4.5 pounds.
Note that this product is obsolete and availability varies. We now try to source any New Old Stock units that we can find in UK. Sometimes these have surface rust that we blast off the part before supplying.
