I have 2 different shocks that came with my bike, one on the bike and the other in a box. The one that came on the bike is a Showa model# mv9-661 it has the hose with canister attached. The other shock is Showa model# mv9003. This one is just the shock pressured up with nitrogen, no canister or anything. I was wondering if anybody could shed some light on which shock might be the better of the two? Any input would be awsome..

 

The shock with the resevoir and additional adjustment screw is from a 94 F2 or an F3 and is a common upgrade over the stock F2 shock

 

thank you..
