After much thought after riding again after 18 years off a bike, it seems to me there are 2 was of setting up your bike today.
1) The new way, people ride more forward with handlebars rotated forward, and to compensate for that, they are running more rear end sag (105mm or more), and more static sag (about 35mm). I don't like the way the front end feel in corners with the bars up that high so I went back to our old set up.
2) rotate the bars back down so the ends of the grips are pointing down a bit, (corners so much easier for me), and get the sag set between 95-100mm, with the static sag at about 20-25mm.)
I see a lot of amateur kids with go-pros on the modern tall bikes with high bars, who can't corner worth a crap, and pretty much have to have a berm to turn at all. Even in the C class in the 80's, there would be a couple of slow guys, but I have never seen so many slow guys in the corners as I do today. Like everybody.

Could you do one on front spring pre load? KYB.

[EarthSurferUSA]

My YZ250 has 2mm of a friction zone. If it had 5 mm, I think I would make sure the linkage and swing arm pivot are greased well.
The shock length can change with a pre-load adjustment? The rider is in a slightly different position, (or ate, took a dump, etc.), for the other measurement. Have you ever read the "Motorcycle suspension bible" by Paul Thede? lol

I understand that you guys are the suspension gurus... but what about free sag? This should of been discussed so that other people have an understanding of whether they have the correct spring rate for their weight.

Is this asfalt only or would that completely change these settings?

[BajaTravelerXRR]

How about free sag? I've been setting my sag up for 35 years and was scratching my head when the expert was calling out numbers? What was he talking about?

[BajaTravelerXRR]

Why worry about pulling a measurement from the center of the axle? Unless the end of the tape fits snug its going to be hard to get the center everytime. Clip the axle nut seems much more logical, but I'm not the "expert". I hope they rebuild bettter than they set up.

I need a stiffer ride. to much sag in rear suspension. I’m 225 lbs so I don’t know if I need to buy a stiffer spring or just do the math and adjust accordingly. Also need to adjust the front suspension for a an overall more sporty ride. Any help much appreciated. I have a 2022 gas gas Mc 450f with WP suspension.

I am 220 pounds. How do I calculate my SAG number?

How would I calculate it for somebody who is 150 pounds?

[Vank]

My sag is 55mm. I just ordered Race Tech 5.4kg shock spring. I weigh 155lbs. Am I going in the right direction? Should I get the gold valve also?

[andrewauman]

Ok this still doesnt answer where your sag should be set at 😅

You should at least mention checking the static sag after doing the rider (dynamic) sag. Status is the sag from extended to compressed just by the weight of the bike, no rider. If your manual says the bike is equipped with a rear spring for say a 165 lb rider and that’s not you, then you go adjust your dynamic sag, then your setup may end up too far from acceptable, because you’re too light, or more likely too heavy, say 200lbs.

And my PHAMZ, and I, "Own KTM!" Cannot claim - any of thee - ABOVE! YZ= frame || HRC motor!
They didn't mention - any YZ chas? Not even - them crazy AMA! AMA = "I attacked eu!"
