Honestly don't even know what a KLR is, but think the Burgman 400 kicks butt from everything I have read...
Will a 400 be big enough for your highway riding? I only have a 125 Agility, but love the thought of more!
Committed to new? Watch craigslist. There are always Burmans (650s and 400s) for sale, but perhaps money is no object...
Either way, my guess is you will love the scooter, but I like Klaviator's answer that one is not enough. Perhaps if you buy used, you won't need to trade the KLR (whatever it is! :)). I can't wait to see the picture of your new bike!

Have fun and enjoy the ride!
