One suspension set up

Looking some advice. Just bought a 2017 crossrunner and want to set the suspension for a two up tour with about 40 kgs of luggage including panniers and box.
Measured sag at standard setting at 65mm but with shock preload full at 29 clicks it is 80mm sag. Does anyone have a good setting for rear and front adjustment of standard shock and forks. Thanks for any help.

OK. How are you measuring sag? Can you briefly describe your method, please? 65mm of sag is an awful lot. If you’re doing it correctly, your shock is in good order and you’re still getting that, no amount of preload adjustment is going to help - you’re going to need a spring to match the job. What weight are you and your passenger? How is the front suspension sag looking?

Bike just out of showroom covered 40 miles, two points used one on rear axle hub and another on subframe bike unloaded measurement taken, i then measure same two points with me on the bike 65 mm difference at standard.
Same method used with pillion also on and preload adjusted turned fully clockwise roughly 22 clicks from standard setting 29 clicks in total
Front sag measured using cable tie method at 41mm. 12 stone each.

So that’s unloaded as in each wheel off the ground, or unloaded as in the suspension bearing the weight of the bike only?

Concentrating on the rear for the moment, standard settings, 12 stone and 65mm of sag? It still seems a lot. Hondas do tend to be under sprung and over damped, but... What’s the total suspension travel from top to bottom of stroke? You want to be aiming to use 1/4 to 1/3 of the available travel. 65mm would indicate between 195mm and 260mm. I’ll guess your rear travel might be fairly generous - in the region of 145mm(?), suggesting a sag with rider on board in riding gear and in riding position of roughly around 36mm to 48mm if my thinking is correct. If! Put another way, if I’m in the right ball park with the actual travel available, you’re currently using about 45% just riding solo on standard settings.

Where’s Mr Cowley?:)

Sounds like you need to start a fresh with your settings at base . Generally when adding a pillion I only add 2-4 turns of extra preload .I have found it far more vital to adjust the rebound/compression adjuster on the bottom of the Shock to stabilise the rear and still give a composed ride . Regarding the front for comforts sake I have left it with less preload ,yes under heavy braking there is dive but it's very controlled . Rider and pillion with luggage 30stone .

I found this with my'99 in that I had it at full, it was stupidly hard/uncomfortable and still exceeded the desired sag.
This was just solo. I ended up backing it down 2 and living with the sag.

Sorry guy's but I have only just read this, first of all what is the length of the stroke of the front forks. For road use you should be looking at 25 to 30% of the length of the stroke for the front sag, That's just the motorcycle sat on its own weight. The rear again depends on the length of the stroke.

This setup works for me and the conditions I ride in ,up front I have 1 turn from max on the compression/rebound and 1 ring showing on the preload . Rear shock preload 7 turns from Max and compression/rebound 1 1/2 turns from Max . This gives the best compromise over all but the hardest of bumps and a comfy ride for 2 up with luggage. The main thing is it stays composed when you want to push on and mentally you are led to believe you need it all set up really stiff ,when really you do not ,just look at all those BMW gs riders especially the cops in the uk how well those handle on softer suspension .
