Q. Can I go for long rides on street 180 say 400kms non stop?

You can do long rides... but the thing is without any break 400-500 km could make you too much tired and you can have pain in your shoulder, neck, hands ,back & legs too. It's better to take a tea break or wash your face have water after every 150 -200km. By this process you can ride for long time and your engine won't get much pressure.

I never tried to go avenger 180 on long drive because I am confident on this bike. I am afraid to go for long distance due to performance of avenger 180

If you don't have any back pain or any other injury. You can ride non stop. If had plenty of water so you have to stop for nature's call.😁
