What's the better bike?

I'm torn between the honda CBR500R and the Cbr500x. I want something with a slight sportiness too it but I also would like something comfy as I'm 6ft 4 and don't want to be too cramped on long rides. Obviously, the X is the comfort and the R is the sport but am I loosing any performance with the X or loosing any comfort with the R if that makes sense?

They're sh/t.
You'll be better off on GS650/800.
You can higher/adjust the suspension.

Cbr650f is a really comfortable bike it's a cross between a touring and sport

Realistically you only rarely use the full performance of a bike. Where I live I could arrange test rides on both, so that is what I would do. My preference would be for the taller bike as I'm tall too and I prefer the ability to see over the top of cars, the payoff is that the taller seating position sometimes discourages you from using the performance.

Ever go down a dirt road? Get the X.

Eenie, meanie, minie, moe.

If want a bike that is comfy and performs well (if you're a hot-dog) than buy my Triumph Tiger 955i. I race both dirt and track and love touring and that Tiger is a mix in-between (have surprised a few sport-bikers in the twisties) and is pretty good on the long-hauls.
