I have a 2012 1200GS that I really like. There are only two areas where I would like to have improvement. They are suspension adjustment, and throttle response off idle in off road situations. I'm thinking of getting a 2017, but wondering if the 2018 model is going to have some drastic improvements, like maybe under seat gas tank, or anything that is going to give the 1200GS a big leap forward. Does anyone have suggestions about this?
