I would still go find a suspension expert. Some of these guys spend their entire lives messing with suspension. There really is no substitute for that.

That spring should work well for you.

Although I'm not quite following the sag measurements you took. The R6 handles well between 30-35mm of rider sag. Shoot for something in that range, and THEN check for free sag. Should be between 5-10 mm optimally if the spring is in the correct rate range. But that model shock is one of the best in my opinion, and will offer you a good range of adjustment (sag aside due to the hydraulic preload adjuster).

Hello Dan,

the Measurements I took
are from the rear axle to a point on my tail.
558mm fully extended topped out, Bike on Foot Peg Stands so the wheel is not touching the ground.

bike on the ground without rider 557mm
and 555mm with rider on the bike
the ohlins Spring I have is the 1093-31/95 and should be the right one for me.

175lbs street clothes 183lbs with full gear.

When I back off the preload adjuster all the way nothing happens, but if I turn it in it's as stiff as a board.

Could this be a issue? No installed Preload? My spring not installed is 150mm and installed is also 150mm. Should I have 10mm installed Preload?

Also I have 2 of the Ohlins ride height shims so that equals 5mm+

Your sag numbers are exactly where I want to be. 30-35mm of rider sag and free sag. 5-10 mm but don't know how to get there from the numbers I have now.

Those measurements are not at all making any sense. And if you have no preload for set length on the spring, that's not a good thing either. Best advice I can think of is hit someone who does this for a living. Without seeing the bike/shock, I can't go off what you are posting as measurements and claiming to have 30/35 mm of sag.

Yes Dan those numbers don't make sense to me either.
Let me clarify what I really want to know. How important in installed preload? What is the range that people are using.

as I stated. the spring length is 150mm uninstalled and installed on the shock is also 150mm so should I spin the collar rings down 10mm-15mm to have 140mm-135mm INSTALLED PRELOAD?

Also do the Ohlins Ride height spacers the blue anodized ones supplied by ohlins affect setting up your SAG/ride height?

ride height shims do nothing to sag. they just increase the overall shock length and raise or lower the bake of the bike. If that shock has a ride height adjuster at the bottom, that has nothing to do with sag.. the only things affecting sag, be it free sag, or rider sag, are the spring rate and the preload.

how about a PHOTO of the shock, i don't have an ohlins catalog at my fingertips, so i don't know if that shock is a hydro preload adjuster, or a collar you turn manually. if a hydro, and you can't get your sag settings with the adjuter turned all the way.. the collar needs repositioned by a PROFESSIONAL. I have been in that situation, where turning the hydro adjuster all the way i couldn't get the sag i needed. One reason i like the manual collars.. can move it where ever you want, AND can change springs easier.

35 rider sag is a nice street number, but 25 is more of a track/racing rider sag number. I totally agree that you would like to see some free sag in the 5-10mm range.
