Q. Does the chain and sprockets last long - Pulsar NS200?

Bro I have hanged it 3 times already each one lasted 15k to 17k kms my bike still look as good as new its like this when you go through p*t and the chain makes noise and you realize that the chain is tight but still make noise in potholes that the time when you should replace the chain sprocket if you stretch it till you start getting that chain noise like its got completely the shaft thst hold the 13 teeth smaller sprocket will get affected and you don't that to happen to you bike believe me

This is a big issue of what I have heard of NS or other Bajaj bikes. They eat sprocket as its an exposed chain system. Keep it clean and keep it well lubricated, it can last a little longer

I am using Stock Ns chain sprocket for more than 26000 kms still it runs good no noise and vibrations need to clean the chain sprocket every 500 to 600 kms and lub it properly
