We discovered this tool after searching for years for an answer to the problem of fitting pistons in bores. We initially bought a pair of sets to fit the pistons on a Kawasaki Z110 0 shaft which had been bored out for high compression aftermarket pistons and had virtually no lead into the bore. (See the video on installing pistons) The tool proved to be fantastic and very much got our seal of approval. We were sceptical at first, but the proof is in the pudding, and we have sold literally hundreds and had very good feedback! The tool is suitable for pistons from 40mm diameter to 85mm. Show more
