i sold my versys and bought a klr. The versys is a better street bike if you want to do track days, or like to go fast. However, my 11 klr can keep up with most riders on normal everyday streets even when we start riding harder. I do know that the new model klr is a better street bike than the old one tho so it is prolly a different story in your situation. I get slightly better mpgs on the klr but i love the extra 80+ mile range. the reasons i switch to the klr are...
1) way better weather protection (again something that you would prolly disagree with because of gen 1 factor)
2) i am in new england and the roads get pretty nasty during the spring months and its nice having a little more travel in the suspension.
3) the versys might be a versatile system but the klr is even more versatile (off road aspect)
4) riding position on the klr is perfect for me, i am 6'4" and have pretty long legs love the extra leg room (seat comfort is about the same stock)
5) right now i can only have 2 bikes mine and the wife's tu250x so with the klr i have a perfect compromise for all riding conditions (see item 3) and i figure with the low operating cost of the klr i will be able to convince her that its worth keeping when its time for a different bike
1) friggin awesome motor for the price point. great pull all over the rev range and can really get you moving quick when you want to.
2) very good suspension for the price point. Very planted and besides the tu250 i havent ridden a bike thats easier to push through the twisties at a fast pace. gets a little bumpy in the spring around here tho
3)riding position is pretty comfy but wish i had more room to move around on the seat, leg room is a little tight for me but wouldnt change it because it gives great lean angle room.
For distance riding if you dont mind the lack of weather protection all you would need is some highway pegs and a new saddle. but if you want to start hitting some trails remember its got and under chassis exhaust so protecting that is a must and the stock tires just wont do on anything but a dry street. Also, a radiator guard and/or fenda extenda in the front. hand guards too
