Royal Enfield Thunderbird 350X 2018-2020 Mileage Tips

Air pressure vs Fuel economy

Keeping your car's tyre pressure at the recommended level improves fuel economy by up to 5%. Underinflated tyres create drag, causing the engine to work harder. Check air pressure every two weeks and before long trips. Slightly higher pressure (by 1-2 PSI) for highway drives can further boost mileage.

Does timely servicing help?

Mixed Experience

This bike is great for both long drives and city rides, offering a comfortable and smooth experience on the road. However, it does come with high maintenance costs. The average mileage is between 30 to 40 km/l. I own the BS4 model, which has some drawbacks such as noticeable vibrations and an engine knocking sound.

Very good bike. Recently changed Rear tyre. Insurance valid. Additional lighting added. Comfortable bike design. Good mileage, nearly 40 on high ways. Pillion also feels good sitting experience. Both tyres have Disc brakes.
