Setting Sag

Recommended Posts

Evill_Ed

Looking for feedback and advice while I am setting the Sag on my new suspension.  My bike will be used 50/50 for Street / Track Days.

I have a K-Razo RR rear shock and AP Motoarts linkage. I can get the rear set up with 10 mm free Sag from the bike weight and a total of  40 mm with me at full gear weight of 192 lbs. If I go to 30 mm total Sag, I basically lose any free Sag. At 35 mm total Sag , I have approximately 5 mm free Sag.  I like the 35 mm setting.

My forks have Ohlins NIX22 cartridges which came with 9.5 N/mm springs. With no added preload, I can get 18mm of free Sag and a total  Sag of 30mm. I think I'm just on the edge of spring ratings for my weight. I'd like to be able to get 35mm total sag in the front too. I think I need 9.0 N/mm springs, or a combination of 90 and 95 to get 9.25 N/mm Spring Rate 

Thoughts?

STOP playing with it or it will fall off!

Seriously, you're pretty close where you're at. I'd be inclined to ride it some and see where you're at, I think it's gonna be about right. At least if you ride her some you'll be able to make a more informed decision about what, if any, changes you'd like to make.  

Signed, the poster child for can't leave well enough alone...

I'm tryin' Moss, but I just can't keep my hands off of it 😁

I do need to ride it to see how it feels. My concern is more about will there be any ill handling (dangerous) effects if the front springs are too stiff. (Flashing back to a bad experience years ago with the wrong fork springs and a bad set up).

Re-measured and made some small adjustments tonight, now all seems good. I have 5mm fee sag in the rear and 30 mm static sag for a total sag of 35 mm.

The front has 7 mm installed preload and 0 mm added preload at adjusters (adjusters provide up to 15 mm additional preload). I get 22 mm free sag and 13 mm static sag for a total sag of 35 mm.

so now I'm happy. I'm hoping to get to ride it to this weekend to see how it all feels.
