29"...it matters!
Never tried one of the lowering kits but I did have a custom seat on the first one I had that lowered it a bit. Problem with that one was I sat in a little "pocket" right on the bottom of the gas tank. Very uncomfortable on a bumpy ride.
But the price is really right on the KLRs, that's for sure. The first one I bought was an 08 with less than 3k miles on the odo and it came with the custom seat, a full set of Kawasaki luggage, heated grips and a nice tank bag.
Didn't really care for it too much but I broke down and bought another one about a year after selling the first one. This one was an 03 with 1200 miles on it. Showroom condition. Actually, picked up 2 of them in virtually the same condition with about the same miles. They were identical twins. 2nd one had about 2200 miles on it and I gave that one to my son.
There are some great deals on the KLRs if you look. Especially on a 2 or 3 year old bike.
You just can't have too many motorcycles.
