I have about 400 miles on my 2017 RC 390 and the chain is very loose and lower part of the chain touches swingarm if I move it; it was like this from the day one. Is it normal, if not how much slack it should have?

I don’t know how hard you push your bike. But my rule of thumb is give as much slack without skipping a tooth. Touching the swingarm isn’t in and of itself an issue.
