At a petrol price of Rs393.64 per litre, a 125cc motorcycle that returns 40km per litre costs about Rs9.84 per kilometre in fuel. Your real result depends on traffic, maintenance, riding style and the actual average of your bike.
The simple calculation
Fuel cost per kilometre = petrol price ÷ fuel average. Using Rs393.64 and 40km/L: Rs393.64 ÷ 40 = Rs9.84 per km.
A monthly commute example
A 30km daily return journey for 26 working days totals 780km. At 40km/L, that uses 19.5 litres. At Rs393.64/L, the estimated monthly petrol cost is Rs7,676.
How to get your own figure
Fill the tank, note the odometer, ride normally, then refill at the next tank. Divide kilometres travelled by litres refilled. That measured average is more useful than a claim on a spec sheet.
