Nature, welcome, the KLR is the perfect all around machine, but it has it's limitations and you are asking it to get upto and possibly past the major one, speed! Yes it will run at the 80 plus but not for long imho without it feeling abused so to speak, better to drop to 70ish and tke that extra 10 minutes per hour to get to where you are going, it will thank you in the long run. As for the rest, I still say do the DOO, many say don't bother any more but hey, it's a cheap mechanical advantage when using the torsion spring and huge peaceof mind for not much $$. The rest is a personal feeling, seat will depend on your weight and age I bet, us old larger framed guys,( I told off for calling us fat) will require a more solid seat maybe I do.....also setting up the handle bars, pegs etc all depends upon your size.....the bike is almost perfect out of the box, but ther is alwasy ways to make it better. There are so many after market products to solve every issue you can think of but the speed requirement you have suggested. It's not a V-Strom in relationship to highway speeds. Just allow for the extra 10 minutes per hour and you'll be golden!
