The KTM RC 390 and Yamaha R3 are two of the most popular sportbikes in the market, known for their thrilling performance and aggressive styling. One of the key factors that riders consider when comparing these bikes is their top speed. In this blog post, we will delve into the top speed capabilities of the KTM RC 390 and Yamaha R3, exploring their engine specifications, aerodynamic designs, and other factors that influence their speed potential.

Top Speed Comparison

KTM RC 390:

  • Top Speed: 172 km/h (107 mph)

Yamaha R3:

  • Top Speed: 190 km/h (118 mph)

As you can see, the Yamaha R3 has a clear advantage in terms of top speed. It can reach a maximum speed of 190 km/h, while the KTM RC 390 tops out at 172 km/h. This difference is attributed to several factors, including:

Engine Specifications

The Yamaha R3 is equipped with a 321cc liquid-cooled parallel-twin engine, which produces more power and torque than the KTM RC 390’s 373cc single-cylinder engine. The R3’s engine is capable of delivering 42 hp at 10,750 rpm and 29.6 Nm of torque at 9,000 rpm. In contrast, the RC 390’s engine produces 43 hp at 9,000 rpm and 35 Nm of torque at 7,000 rpm.

Aerodynamic Design

The Yamaha R3 features a more aerodynamic design than the KTM RC 390. Its sleek fairing and low-slung profile reduce wind resistance, allowing it to achieve higher speeds with less effort. The KTM RC 390, on the other hand, has a more upright riding position and less aggressive fairings, which contribute to its lower top speed.

Other Factors Influencing Top Speed

In addition to engine specifications and aerodynamic design, several other factors can influence the top speed of a motorcycle, including:

  • Weight: A lighter motorcycle will have a higher top speed than a heavier one. The KTM RC 390 weighs 155 kg (342 lbs), while the Yamaha R3 weighs 169 kg (373 lbs).
  • Tire Size: Wider tires provide more grip but also increase rolling resistance, which can affect top speed. The KTM RC 390 comes with 110/70-17 front and 150/60-17 rear tires, while the Yamaha R3 uses 110/70-17 front and 140/70-17 rear tires.
  • Gearing: The gearing of a motorcycle can be adjusted to optimize acceleration or top speed. The KTM RC 390 has a shorter final drive ratio than the Yamaha R3, which gives it better acceleration but sacrifices some top speed.

Final Thoughts: Top Speed Champion

Based on the factors discussed above, the Yamaha R3 emerges as the clear winner in terms of top speed. Its powerful engine, aerodynamic design, and lighter weight allow it to reach a maximum speed of 190 km/h, while the KTM RC 390 tops out at 172 km/h. However, it’s important to note that top speed is just one aspect of a motorcycle’s performance. Other factors, such as handling, acceleration, and fuel efficiency, should also be considered when choosing a bike.
