Here we have a set of standard aftermarket replacement piston rings for the Honda CBX & CB900 DOHC, we have used many of these sets in our rebuilds and have compared them to the OE ring set and NPR to ensure a quality product as we know a lot of rebuilders question aftermarket ring quality.
In our view after careful examination, they meet or exceed the fit of both in terms of fit and ring compression as measured by us. The second compression ring is 0.3mm thinner in the width than the OE but exceeds or matches the others compared products for ring compression.
4 sets required for the CB900 1979 > 1982
6 sets required for the CBX1000 1978 >1982
