The knob of the Pulsar AS150 presents a little bit of confusion but twisting the circle into the right direction till the 'RES' comes before the arrow is the position for setting the bike into reserve. The 'ON' symbol can again be used if the knob is twisted to the extreme left. The bike comes with a 12 liter fuel tank, out of which the reserve fuel tank is 2.4 liter. The bike returns a mileage of 45 kmpl, making it good for 500 + km on a single refill.
