set rings
Re: set rings
Compression and nose rings are 2mm thick, oil scraper ring is 4 mm thick. We would highl recommend that you obtain a work shop manual (01 59 9 099 176), and the original BMW parts catalogue for R26 to R69S models (01 09 9 099 161).
Best bet is to order two piston ring sets and don't forget to state for what diameter piston or bore.
