Yes weight has to do with preload, rebound, compression, SAG, but not geometry. I ride some with Geoff May and he gave me the starting point geometry numbers for the rx. With front end picked up with a head lift stand tire off the ground and forks fully extended measure 485mm from the top of the lower triple tree to center of the front axle, rear shock 322mm eye to eye from there adjust according to the track +/- mm increments.

If you set up according to the numbers up top you should have 27mm of fork above the top tree. Measure from the top of the tree to top of the fork. For the street use the lower reference line place the line even with the top of the tree.
