How stiff is the rear coil on a 2017 AT?

I can probably live with the soft front end on my bike but really think I need a stiffer setup in the rear. I would say a rear coil that is 10% to 15% stiffer than stock which will likely require a valving change as well. Given that the two together will likely cost $400, I may just buy a whole new rear shock absorber but don't know how stiff a coil I need since I don't know if the stocker is a 9.0kg/mm, 9.5kg/mm, 10kg/mm, 10.5 kg/mm etc.

Anyone know for certain?

I’d say; decide on the shock you want then email the manufacturer with the normal load weight and expected max weight ( with panniers and luggage extra passenger) and your riding style, like, a grandma or motocross or something in between. They designed them, they can tell you exactly what one would be best for you, much better than someone tinkering around in his/her garage...
I know that wasn’t your original question but jus throwing that out there, they would know just what the stock one is too and give the best advice for the cash you are about to drop...

The stock spring is 8.3kg/mm, according to TeknikMotorsport. See here: https://www.teknikmotorsport.com/Hon...n-modification

Good idea. I'll just tell them what I need and trust them to set it where it should be.

I wouldn't. Know what the stock spring rate is and decide if you want softer or stiffer. Then, see what you can get with the replacement shock.

If you go on Race Tech website for the AT it will show stock spring rates & various other spring rates
