This iconic bike has been a staple on Indian roads since its introduction in the 1980s and has captured the imagination of riders with its sleek design, peppy engine, and agile handling. Among the many questions that enthusiasts often debate about is the top speed of this beloved bike. In this article, we’ll delve into the world of the Yamaha RX 135 and explore its maximum velocity, while also discussing the factors that influence its speed and the modifications that can help unlock its full potential.
The Stock Speed of Yamaha RX 135
The Yamaha RX 135, with its 134cc, 2-stroke, single-cylinder engine, is known for its peppiness and agility. In its stock form, the bike is capable of reaching a top speed of around 110-115 km/h (68-71 mph). This may not seem like much by today’s standards, but for a bike of its class and era, it was quite impressive. The RX 135’s engine produces 11 horsepower and 10.4 Nm of torque, which enables it to accelerate quickly from 0-60 km/h in just 5.5 seconds.
The Factors Affecting Top Speed
While the stock top speed of the RX 135 is around 110-115 km/h, various factors can influence its maximum velocity. Some of the key factors that affect the top speed of the bike include:
Engine Tuning and Modifications
One of the most significant factors that can impact the top speed of the RX 135 is the engine tuning and modifications. A well-tuned engine with the correct carburetor setting, air filter, and spark plug can significantly improve the bike’s acceleration and top speed. Additionally, modifications such as installing a performance exhaust, high-compression pistons, and porting the engine can also enhance the bike’s speed.
Rider Weight and Position
The weight and position of the rider can also affect the top speed of the RX 135. A lighter rider can expect to achieve a higher top speed compared to a heavier rider, as the bike’s power-to-weight ratio is more favorable. Furthermore, the rider’s position on the bike can also impact aerodynamics, with a more streamlined position allowing for better air penetration and higher speeds.
Tire Pressure and Quality
The tire pressure and quality can also influence the top speed of the RX 135. Properly inflated tires with good grip and tread can provide better traction, allowing the bike to accelerate and maintain higher speeds. On the other hand, underinflated or low-quality tires can result in reduced speeds and compromised handling.
Aerodynamics and Air Resistance
The aerodynamics and air resistance of the bike can also impact its top speed. The RX 135’s design, with its sleek fairing and windshield, helps to reduce air resistance and improve aerodynamics. However, the addition of accessories such as windscreens, crash guards, and luggage carriers can increase air resistance and reduce top speed.
Unlocking the Full Potential of RX 135
While the stock top speed of the RX 135 is around 110-115 km/h, many enthusiasts have been able to unlock the bike’s full potential through modifications and fine-tuning. Some of the ways to increase the top speed of the RX 135 include:
