Thanks for the informative video. I have a Duke 390 and the manual says 14mm static sag and 47mm riding sag. I found a point above the rear axle that is exactly 600mm from the axle. I adjusted the shock preload +3 (i.e. 8/10) because I am 100kg plus riding gear. I am now getting riding sag ~47mm which is great but running 8/10 preload is obviously going to reduce static sag below the 14mm in the KTM spec. Does static sag even matter? The bike isn't going to ride by itself. It needs me on it in which case the riding sag is applicable. Is that correct? Also does 8/10 sound about right for my weight or do you think I should go down a notch?
My experience brief as its is id ktm are all front lol. No one answering your question from them when only 5 comments isn't a surprise. They don't even have an Indian manual for my bike (their are differences) but everyone else can download one lol. Company sucks.
What if your static sag needs adjustment? How does that work.? And if get this right you say you use the unsprung measure ment when it's on the stand and subtract the measurement of when the rider is sitting on the bike to calculate find rider sag? The static sag thing throws me off when measuring the rider sag
Static sag is with the rider off the bike and is used to determine if the spring rate is right for you weight. So static will be the measurement with the bike on the stand and then with the bike under is own weight. If static is 20mm or less you need a stiffer spring. 40mm or more you need a softer spring.
To get the rider sag measurement you measure with the rider on the bike and take the measurement with the bike on the stand (rear wheel off the groud) subtract these two measurements and that will give your rider sag.
best guide outthere i been look at all of them
no one showed with a tape
thank you so much dude

No centre stand makes it bit difficult for a novice and shop hrte has no idea.they don't even have a manual. I kid you not
