First, you must be talking about a K
1200LT, and did you mean $5.8K?
There have been quite a few inseam challenged people who have learned to love the LT, but it will take some practice and the desire to overcome it for the joy that can be obtained from it.
It certainly is best to have at least a 29" inseam. In 2005 BMW changed the seat on the LT to make it easier for the less tall people, but the change also made the seat less comfortable for the taller rider.
The LT is a bit of a hand full at walking speeds, but once one learns the ways to handle it the problems just sort of melt away.
Trying to lower the LT is not a great thing to do. It handles great, and for a large bike is really good in the twisties. Lowering it would detract from that, and the bike would then not be what most of us love about it.
You have to test ride one to see if it seems that it would be what you want AFTER a little learning curve. At first, it may be a little daunting, but most of us went through that.
