Rear preload\Sag 2010 SP - Ducati.ms

All;
I have been reading the suspension threads on this forum and started setting mine up today. I have a question on preload. I weigh about 200lbs. With the rear wheel off the ground (bike supported with jack stands at the swingarm pivot) I have a measurement of 530mm from a point on the CF side panel to a fixed point on the axle.

With me on it the average length between the same points is 486mm for a SAG of 44mm. The free sag is 15mm. I cranked in about 4 turns of the preload collar to get to this point. From the end of the threads to the top of the lock collar I have approximately 19mm showing.

From what I have read here the free sag should be 5-10mm and the sag should be approximately 30mm. It seems that if I cranked in enough preload to get to 30mm sag I would be topped out.

Does the hyper need a heavier spring for a 200lb rider?
Michael

Hey Michael, I seem to be in the same boat as yourself.
Did you end up finding out a solution?

Good question. About 195 and with a loaded backpack today I swear felt like the ass of the bike was squatting too much today under some conditions.

No, I have to admit that those settings are working pretty well after I went to 5wt fork oil. I do plan to get .8kg springs for the front and then revisit the rear

For my skill level (slooow) I'm pretty right happy now.

most rear shock springs are rated for a 165 to 185lbs guy ,so imo one rate higher would work better for you.

now for the 796,its spring in the rear is softer then the 1100 rear spring as i have both shocks. i weigh 185 with gear and the stock 796 spring was to soft to set the sag just right,once i replaced it with the shock from a 1100 it was perfect.796 owners dont forget to do this mod you will need to move your O2 sensor cause it will hit the reservoir of the new shock.
