Hi does anyone have the oem piston ring thickness for an 08?
Just trying to sort a piston/ ring mismatch and the info would be helpful.

Thanks

Sam

Hi Sam,
Well I have seen written down that Honda has changed rings thickness several times.
Rings have tended to get thinner to maintain a seal as power has increased.
The 2006-2007 rings are 0.72mm
The 2008-2009 rings are 0.85mm

Are you using a factory or aftermarket piston.
If you are using and aftermarket that has been around a while they may have stayed with the thinner ring.

If you are using aftermarket piston then contact the maker.
They probably based their piston on a particular year and should be able to tell you what oem rings fit.
