Q. Is Bajaj 2019 Dominar 400 good bike for a beginner who is upgrading from Activa?

It is my first motorcycle, I have not ridden a motorcycle before in my life, my previous experience is with a small car and a mountain bike. I started three months ago, now I do routes of 40 minutes to an hour, in the city and on the highway, my maximum speed based on my little experience has been 150 km / h maximum, both during the day, night or light rains and storms, at the moment very noble very docile when you control your clutch and throttle well. In short, YES IT IS A GOOD MOTORCYCLE FOR BEGINNERS, it depends on your motivation to develop your skills and ride, in my case I can tell you that the best thing is to hit the road.

Not recommended bro. Why because weight is double and power of bike is like too high. As a active rider you can't control the bike because of 8x power than your Activa. Buy a 250 or 200cc bike and have some experience . Then buy Dominor

Depends if you have any experience of riding other bikes such as r15 or ktm 200
