I have both too; they are two very different bikes. I almost didn't bother buying the Versys thinking the KLR would be "good enough" to commute around with but I'm glad I bought the V as well; it's a WAY better street bike - better handling, brakes, and most importantly: power.
OTOH, I still use the KLR for real dual sport use and it's far superior to the V for that...
