To improve the mileage of the TVS Apache RTR 160 2V, 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 throttle inputs and anticipating traffic flow. Reducing excess weight by carrying only essential items is also vital, as less weight equals less work for the engine. Additionally, using aerodynamic accessories like a windscreen or full-face helmet can help reduce air drag. By staying on highways where possible, which typically have less traffic and fewer turns, you can also maintain better fuel efficiency. These strategies can help optimize your motorcycle's performance and fuel economy, potentially increasing the mileage from the average 45-50 km/l to even higher figures with consistent practice and maintenance.
