I've got the leaky fork syndrome and I'm trying to debate what to do. I've heard they made some improvements to the fork for 2017 so I compared the part fiches and it looks like they changed two things. 1) a revised oil seal, and 2) they added what they call a scraper between the oil seal and the dust seal. Should I get these items and do a rebuild or transition to something aftermarket like the SKF's? I don't understand what makes these so different from the 450F forks from a seal perspective?
