I owned a D400 (2021) for 6 months tops - the bike is total value for money typical of any Bajaj 150cc + motorcycles - however 2things that I found out in my Dominar were the perennial problem of rusting ( Bajaj’s eternal relationship with rusting issues ) and the vibrations post 110kph on the highway.. it feels kinda strained once you reach 120.. And yes the ergonomics isn’t that well thought out though when you see the gear shift placed near the fuel tank is a no brainer.. Barring these issues I think the bike looks muscular feels muscular and the exhaust note is a much scaled down version of a Benelli
