I have an Apache RTR 160. Bought it 3 months back and have covered 3300 kms.

My bike finds it very hard to revv above 4k rpm and it feels like engine is going to blast after 5k rpm. Problem is in all the 1-4 gears except the 5th. Therefore I am scared to cross 6k rpm on these gears.

This problem I found after 1000 kms as before that I never revved my bike above 4k rpm. In 2nd service I told about this problem and they said they will solve but still I am getting this problem.

The experts kindly help me with this, I am really scared now as its my first bike.

Thanks in advance.
