Fork oil is confusing because we've always gone on 10w or 15w etc but someone said it's about 'centistokes' or something like that anyway and he was putting 2.5w oil into FJR1300 forks because of this centistoke factor. I can't really say I understood what the Foc he was on about so I just bought some 10 and 15 and mixed them to make 12.5 ish.
