Okay completing some more research here before I make my final shock decisions. Did some more shock searches and came up with an interesting find. BrentL posted a anacdotal comment about using an XR600 remote resevior shock in a 230 conversion with a USD front end (couldn't remember which XR600R shock he sourced though). I was like So I go to Works Performance's site and take a look, here is what I find: The "Ultra Cross" works shock for the 85-87 XR600R is 15.13 inches (same as CRF230F "Pro Series" works shock) Both the "Pro Series" for the 230 and the XR600R "Ultra Cross" shock are remote resevior shocks. The 230F is a "Pro Series" mini shock with the option of high/low speed compression, but the XR600R shock is an "Ultra Cross" shock with 18 clicker rebound adjustment and high/slow speed compression adjustment. It appears that while the "Pro Series" is a mini shock, it looks like a big boy XR600R "Ultra Cross" shock also will work. Does anybody have any idea whether the Big Boy "Ultra Cross" shock is a better buy suspension wise for the extra $200??? Got me to thinking... Anybody have experience with both the "Pro Series" mini and the "Ultra Cross" Are they the same shock, but mini vs full size applications?
