Great. Thanks for that fantastic advice. S3 piston measurements in the new cylinder should be spot on then?

Hi All Im replacing the piston in my 2013 ossa tr280. I am having trouble finding an oem piston kit anywhere. I did notive that there is a s3 racing piston kit available - has anyone had any experience with this kit? I am also replacing the cylinder or perhaps sending the bore away for rechroming. Its about the same price either way- any thoughts? Thanks for your time Gene
