For most modern Bikes there's no real need to implant high-Comp Racing Pistons,but there are still a few out there, where it makes Sense to drop them in, especially some Italian Bikes and Honda's, which usually have a very conservative compression ratio.
The Pistal Racing Pistons are superior Quality and Craftmanship, I use those Pistons since 12 years, and they never failed.
