Heads up on a hard to find replacement piston on fleabay. First aftermarket piston I have ever seen for the 041 Supers with the 48mm bore. Chinese made "Cross Performance" branded, but the dimensions were excellent on a measured sample I received, when compared to a new OEM 1110-030-2003. The unknown issue is the material, as who knows what the percentage of silicone is the aluminum alloy mix.
