Well I have always loved the BMW bikes, and I have been toying with the idea of trading my bike in on one. I havnt sat on a K bike for a while. U think it is about the same size as the zx. If anyone has been on a K 1300s, could you confirm this maybe. My bike is midnight blue, with 2200 miles, 2008.. I just can't believe the zx is worth such a small amount? The bike looks like a million bucks.. But I did get it for 9k new two years ago. Would like to see around, $7500, trade in is about $6500. So anyone where riden the BMW k 1300s,and would like to compare the two bikes that would be great!
