How the Yamaha MT15, a Low-Cylinder Capacity Bike, Matches the Top Speed of the Bajaj Pulsar NS200

The Yamaha MT15 and Bajaj Pulsar NS200 are both popular motorcycles in the Indian market, but with different engine specifications and characteristics. This article compares how the Yamaha MT15, despite having a lower engine displacement, can match the top speed of the Bajaj Pulsar NS200.

Engine Specifications

Yamaha MT-15: Engine: 155cc single-cylinder liquid-cooled SOHC Power: Approximately 18.4 hp @ 10,000 rpm Torque: Approximately 14.1 Nm @ 8,500 rpm Weight: About 138 kg (kerb weight)

Bajaj Pulsar NS200: Engine: 199.5cc single-cylinder liquid-cooled SOHC Power: Approximately 24.5 hp @ 9,750 rpm Torque: Approximately 18.5 Nm @ 8,000 rpm Weight: About 154 kg (kerb weight)

Factors Contributing to Comparable Top Speed

Power-to-Weight Ratio

The Yamaha MT-15 has a better power-to-weight ratio compared to the Bajaj Pulsar NS200. With its lighter weight and competitive power output, the MT-15 can accelerate quickly and reach higher speeds effectively, which is a key factor in matching the top speed of the NS200.

Aerodynamics

The design of the Yamaha MT-15 features a more aggressive and aerodynamic profile, which can help reduce drag at higher speeds. This is in contrast to the more upright position of the Bajaj Pulsar NS200, which may offer less aerodynamic efficiency.

Transmission and Gear Ratios

The Yamaha MT-15 is equipped with a 6-speed gearbox that allows it to maintain higher RPMs effectively. This contributes to achieving a higher top speed despite its lower displacement. Higher RPMs mean a higher engine speed, which can help deliver more power, especially at higher speeds.

Engine Tuning and Performance

Yamaha has engineered the MT-15's engine for high RPM performance. This tuning is designed to deliver peak power efficiently at higher speeds. This allows the MT-15 to compete with larger displacement bikes in terms of top speed, effectively bridging the gap between its smaller engine and the Bajaj Pulsar NS200.

Rider Skill and Conditions

While rider skill, riding position, and conditions such as wind resistance and road conditions play a significant role in achieving top speed, the MT-15's design and performance capabilities are still a major factor. A skilled rider can undoubtedly extract more performance from the MT-15, even with its smaller engine.

Conclusion

While the Bajaj Pulsar NS200 has a larger engine and higher power output, the lighter weight, better power-to-weight ratio, and aerodynamic design of the Yamaha MT-15 allow it to match or come close to the top speed of the NS200. This makes the MT-15 a compelling option for riders looking for performance in a lightweight package. Whether it's for everyday commuting, leisure riding, or short-distance races, the MT-15 demonstrates a remarkable ability to compete with its larger counterparts.
