Bajaj Pulsar NS200 can be used for 500 kms long rides, but make sure to take regular breaks after every 50-60 kms for 10 minutes which is good for you as well as to the engine. Manage the speed according to the road conditions and maintain the speed of 50 to 55 kmph where the engine will give better performance and good mileage. Keep watch on the tyres at regular intervals.
