I own a 2013 B5 Bullet 500 which is unreliable and requires a lot of maintenance. But the Himalayan is supposed to be a LOT better, and I have seen enough YouTube videos to convince me that it is.
However, just how much of a beginner are you? Have you ever ridden a motorcycle at all? If not I would not buy a bike yet. Take the MSF beginner rider course (they provide the bikes) and see what it's like for you. If you pass the course in most states you get your license without any further tests. If you are big enough to easily get on and off a Himalayan, and flat foot it at stops, then it should be fine as a first bike. If you are on the smaller side, do yourself a favor, buy a cheap used Honda Rebel 250, ride the wheels off that thing until you've got everything down solid, built up your confidence, and believe you are ready for something a little bigger, then sell the Rebel for about what you paid for it and buy something bigger.
