Wilbers
Hello mate
Yes I have fitted Wilbers onto my 1150 adv, I got the same size front one and the one on the rear is the standard gs size which iirc is about 25 mm shorter than the adv shock and this lowered the bike just right for me , weight wise i am about 100 kg give or take and then work out your luggage weight as in what you'd normally take , pillion etc, and tell them and they'll sort it out , some people like to pick a heavier spring but my friend on here Micky advise me to pick the right weight and then you can dial in the preload, good advice it was an all
