To improve the mileage of the TVS Apache RTR E100, focus on several key areas. Regular maintenance is crucial, including routine oil changes, keeping air filters clean, and ensuring brake pads are responsive. Properly inflated tires, as per the manufacturer's recommendations, can significantly enhance fuel efficiency by reducing rolling resistance. Adopt smooth riding techniques by avoiding aggressive acceleration and abrupt braking, instead opting for gradual speed changes. Reducing unnecessary weight on the motorcycle also helps, as excess weight increases the engine's workload. Additionally, utilizing good aerodynamics, such as a windscreen or full-face helmet, can help reduce air drag and improve fuel efficiency. By staying on highways where possible, which typically have less traffic and fewer turns, you can also maintain better fuel economy. Overall, these practices can help optimize the fuel efficiency of your TVS Apache RTR E100.
