Q. When I took the delivery of Bajaj 2019 Dominar 400, the showroom excutive told me to drive slow within the speed of 70kmph, and adviced not to drive above 70kmph, please tell me what to do?

Yes, perfect...In the run in period of 1st 1000 kms, you need to maintain this speed. Or if you can drive based on tachometer, maintain below 4500 rpm. This will be the better way to maintain the bike initiAlly

Better to ride slow in first 5000km, if not mileage will goes down, engine wear and tear, over heating issues and engine vibration issues rises

There is a manual given appropriate speed to gear number if you follow it you can ignore the executive words and enjoy the ride
