We, the wife and I, want a K1200GT between 2000 and 2005 because they are great looking bikes and seem the perfect fit for the kind of riding we like to do, but I am vertically challenged. At 5'7", I need to be able to lower the seat down to about 30". I am sure that I am not the first to want to accomplish this so I am turning to the vast resources of the collective. Is there a way and how much should I expect to pay to accomplish it? Thanks for any advice.
