worked great for Me
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I have only used two patches so far, and they have worked just fine, You do have to have some tools like a buffing wheel and the vulcanizing glue and a roller wheel to make these patches work as they should, but I am happy with these patches, especially since nobody will repair a motorcycle tire, so this is Your only way to fix them.
