Fuel-sipping Superbikes: Ktm Rc 390 Vs Duke 390 Mileage Comparison

When it comes to sporty, high-performance motorcycles, KTM’s RC 390 and Duke 390 stand out as two formidable contenders. Both bikes share the same engine displacement, but offer different riding experiences and, crucially, different mileage figures. In this comprehensive guide, we delve into the KTM RC 390 vs Duke 390 mileage comparison, examining factors that influence fuel efficiency and providing real-world insights to help you make an informed decision.

Engine and Powertrain

The RC 390 and Duke 390 both feature a 373cc single-cylinder engine that produces 43 horsepower and 35 Nm of torque. However, the RC 390’s engine is tuned for higher RPMs, resulting in a sportier power delivery. The Duke 390, on the other hand, has a more relaxed engine character, prioritizing low-end torque for better acceleration off the line.

Aerodynamics

The RC 390’s fully faired design offers superior aerodynamics compared to the naked Duke 390. This reduced drag allows the RC 390 to cut through the air more efficiently, resulting in improved fuel economy at higher speeds.

Weight and Handling

The RC 390 is slightly heavier than the Duke 390, weighing in at 165 kg compared to the Duke’s 154 kg. However, the RC 390’s more aggressive riding position and higher-spec suspension contribute to its superior handling capabilities, particularly on twisty roads.

Riding Style

Riding style has a significant impact on fuel economy. Aggressive riding, characterized by frequent acceleration and hard braking, will consume more fuel compared to a more relaxed, fuel-conscious approach.

Real-World Mileage Figures

According to user reviews and independent tests, the KTM Duke 390 typically delivers a mileage of around 30-35 kmpl in city conditions and 35-40 kmpl on highways. The RC 390, due to its higher RPM range and less aerodynamic design, returns slightly lower mileage figures, typically ranging from 25-30 kmpl in the city and 30-35 kmpl on highways.

Factors Affecting Mileage

Apart from the factors discussed above, several other variables can affect mileage, including:

• Tire pressure: Underinflated tires increase rolling resistance, reducing fuel efficiency.
• Maintenance: Regular maintenance, such as oil changes and air filter cleaning, ensures optimal engine performance and fuel economy.
• Fuel quality: Higher-octane fuel burns more efficiently, resulting in better mileage.
• Traffic conditions: Stop-and-go traffic significantly reduces fuel economy.

Which Bike Offers Better Mileage?

Based on the aforementioned factors, the KTM Duke 390 emerges as the clear winner in terms of mileage. Its relaxed engine character, lower weight, and more upright riding position contribute to its superior fuel efficiency.

The Bottom Line: Mileage Matters

While both the KTM RC 390 and Duke 390 offer exhilarating riding experiences, the Duke 390’s superior mileage makes it a more budget-friendly option for riders who prioritize fuel efficiency. Ultimately, the choice between the RC 390 and Duke 390 depends on individual preferences and riding style.
