I weigh about the same as you guys, but I think the shock spring is too soft.
I tightened the preload to six turns over minimum for my optimum setting, as described in the following thread.

A question regarding the shock spring rate of the RX3 was posted on another forum, and Joe Berk said he was going to research the matter. I am subscribed to that thread, so I will post the information here after Joe replies.
Personally, I would like to purchase a quality, aftermarket shock absorber for the RX3. I think the bike deserves a better shock if it is going to reach its full potential as an adventure motorcycle.
I have heard CSC is working on developing a quality aftermarket shock with a British company. I hope this shock has about 7.5 inches of travel; I don't care if the saddle height is raised a bit.
