Q. Is there any problem like chain sound from Dominar 2019?

That's a big yes.. as it's a 373cc motorcycle and is of a single cylinder... It would give out vibration.. but way much lesser than the ktms... And after covering around 5k kms.. you can feel your dominor getting smooth... Get rid of stock tyres.. as they are always hard... Go with Micheline.. right now I'm experimenting with ceat zoom xl radial tyres... And change from bajaj engine oil to motul.. you would notice great decrease in the vibrations

Brother, no bike is perfect. I had a series of issues in my 2021 Dominar. Bajaj quality is pathetic let me tell you that at least. They provide longer warranties for the same reason. And just an example, the chain costs 3850 to replace and that includes removing the whole rear end, suspension, swing arm, wheel etc just to install the chain. Do you want that kind of headache? I am a Dominar 400 BS6 owner and I am telling these from personal experiences. If you are worried about the hassles then walk away from Bajaj. Just a honest suggestion from a Rider to another.

If chain has luse and not properly l**e then it will definitely sound Thats happened with all bike
