Inline 4 engines have perfect primary balance, unlike singles and most twins. The mild buzz comes from a secondary imbalance when two of the pistons are at the top of the stroke and two are at the bottom. I don't consider it significant. I've done a few 400 mile days and it hasn't been an issue.
I agree. I have a slight buzz in the grips at around 4K but its really minor. My 750 is no doubt about as smooth and smooth can get imo.
