To improve the mileage of the Ducati Panigale V2 Bayliss, focus on regular maintenance by following the manufacturer's service schedule for oil changes, air filter replacements, and spark plug inspections. Ensure proper tire pressure, as under-inflated tires can decrease fuel efficiency. Adopt smooth riding techniques, avoiding aggressive acceleration and abrupt braking, and maintain a steady speed, especially on highways where traffic is less dense. Reduce unnecessary weight by carrying only essential items, and consider using aerodynamic accessories like a windscreen or full-face helmet to minimize air drag. These practices can help optimize fuel efficiency, potentially increasing the average mileage of the Panigale V2 Bayliss, which typically ranges around 35-40 miles per gallon, to even higher levels.
