I am buying a 2003 K 1200 let this week. Bought it off the internet through a reputable dealer but I have never ridden one. I have had a gl 1800 and an ultra classic e-glide and have always dreamed of the BMW. I am about 5' 8'' and am wondering if I am too short for this bike or if I will be ok. Also what model is the stock GPS and can it be updated with current maps. Thanks for any help.
