Assuming your bike gives you about 25-30kmpl, it would cost you around 8000-9000 for the fuel. Apart from that, the food and accomodations would cost you an additional 500-700 per day, which comes ar (Read More)ound to 7-10k per person. So the trip can cost you anywhere between 15-20k. Also, I am assuming that you will be covering Manali as well (obviously), which means the trip will take you at least 2 weeks.
