i believe that diagram is for the showa forks mate, that is the one i was looking at and getting confused over because just off your photo, to the right, is settings which are measured in amount of turns. ie 1 and a half turns out. mine (ohlins) click and couldnt understand why they would give the settings to me in turns. Although on that diagram the little 'reservoir' thing at the bottom, im sure ive only ever seen that on the ohlins ??? confused, but ive set mine to what arryace posted earlier and it all seems tickety boo ...
No that pic is for Ohlins. Showa don't have the external adjuster at the bottom.
All Ohlins R & T forks have compression adjustment at the bottom and rebound at the top as BRG stated. You can debate it all you want but that is the facts. I have the genuine Ohlins manual here in front of me and it concurs with the Aprilia manual.
It's a generic design trait for cartridge forks except some race ohlins have both at the top now.
