The Royal Enfield Bullet 350 typically does not have a specific "reserve capacity" mentioned in its specifications. However, it is worth noting that the Bullet 350 comes with a fuel tank capacity of approximately 13.5 liters (3.56 gallons).
In general, many motorcycles, including the Bullet 350, have a reserve fuel indicator or a reserve fuel valve. When the main fuel level drops to a certain point, typically around 1-2 liters (0.26-0.53 gallons) of fuel remaining, riders can switch to the reserve fuel setting to access the remaining fuel in the tank.
While there isn't a precise reserve capacity mentioned for the Bullet 350, the reserve fuel setting should provide enough fuel to reach a nearby gas station or cover a few extra miles until you can refuel. It's always a good practice to keep an eye on your fuel gauge and refill the tank before the fuel level gets too low to avoid any inconvenience during your ride.
