I am just curious as to if anyone has used these. I am not sure which ones to get so I want some feedback. I have pre-ordered the Ohlins FPK103 pistons but I think a cartridge kit is the better way to go. Like I said I am not sure the + and - of each so I was wondering if people might be able to explain them to me. Also which ones are a direct drop in? The ExtremeTech has lots of adjustment which is nice but I don't know much about the Ohlins 25mm kit or the RaceTech so I was wondering if someone may be able to help me out? Or is the 20mm piston kit (FPK103) the way to go? It is $300 compared to 1200ish. Or is the link 5mm link and shortening the TTX a better way to go? Or are new forks that much better then a cartridge kit?
