Q. Is Jawa 42 comfortable for 5.1 height and 50kg weight?

The 765mm seat height of Jawa makes it supremely accessible for shorter riders. The bike's short-stroke, high-compression motor simply isn't meant for cruising. It revs hard and likes to be kept on the boil, attributes that are unlike any laidback cruiser. And that's what eats into the bike's charm. Moreover, we would suggest you to take a test ride for a better understanding of performance and comfort. Follow the link and select your desired city for dealership details.

I’ll put it this way. Jawa is possibly the most powerful bike with low seat height, in the given price range. At 5’1”, I think you should still be able to toe on both sides. A good riding boot is recommended.

Yes, very comfortable, best for someone between 5 and 5.4. With balanced center of gravity 50kg person can handle it well. My son is 48kg with 5.7ft and he travels 500+ km in single day without handling problems.
