Look like Sachs with adjustable preload to me. Where and how are you measuring the OD?
Only other suggestion I have if they are 45mms is to pull them down and spec up the bushings and seals and then cross reference against some common items.
Thanks for the reply guys! The previos owner was the importer her in Norway and the bike came with ohlins shock rear and six days stickers! I think he had the parts to mix and match a little!
i presumed it was a 300 sixdays but ill find out for sure when the COC papers comes from Spain.
I think these where on the 2010 six days but only the 125`s! Am i right?
