I've owned a KLR and a 400 Burgman. They were pretty close on the highway speed wise, the Burgman having much better wind protection. Neither is that good at high speeds, I always felt like I needed more power till I got a VStrom. Burgman was great for riding to work but not very good on twisty back roads, did not have much suspension travel, not much grunt ou of the corners. Did not feel very fast with the CVT but did ok.
