Q. My height is 195cm is the Harley Davidson Roadster comfortable and suitable for me?

If your purpose is long cruises, something like 400km+ at a stretch, It would not be my first choice .may be i would change the stock handle bar to ape bars. But if u wanna have aggressive short rides or short cruises this bike is a charm. my height is 173cm and I dnt feel uncomfortable on roadster unless I push my rides beyond 300-400 km on a bad day

That's a great height :) take a test ride and see if you are comfortable - shouldn't be an issue - you might need to raise the handle bars

No, not at all. You are so slim, can't bear the weight of that one.
