I am 6'2", which bike would be comfortable for me - Yamaha Fazer or FZ Version 2.0?

Go for FZS V2.0, Nice stylish and Comfortable. Even a guy of my height (6’2”) is very comfortable while riding.

Both the bikes are built on the same platform and have the same power outputs, same seat height and driving dynamics. The Fazer would be a better option for you as its semi faired design provides better wind protection and the dual headlight design looks much better than the naked sibling. It even looks more muscular and would definitely suit your height. The bike is powered by a 149 cc, fuel injected engine producing 12.9 BHP and 12.8 NM of torque. Its new light weight body frame provides better fuel efficiency and improved pick up. It is available for a price tag of INR 86,805.

Quick Facts - Yamaha Fazer Version 2.0 Fi

I'm 6'2" myself. I've found that the FZ is more comfortable compared to the Fazer for tall riders. Also check out the Pulsar 220 and the Hero Karizma, both of which are excellent rides for tall people.
