The Yamaha FZX, also known as the FZ-S in some markets, is a popular motorcycle known for its sporty design and performance. However, vibrations can vary from bike to bike, and it's possible that some models may experience vibrations at specific speeds. It's important to note that individual experiences can differ due to factors such as riding conditions, maintenance, and personal sensitivity to vibrations.
That being said, it is not uncommon for motorcycles, including the FZX/FZ-S, to have some degree of vibration at certain speeds. Vibrations can be influenced by various factors such as engine design, suspension setup, tire condition, and more. Some riders may perceive these vibrations as noticeable, while others may not be as sensitive to them.
If you're experiencing vibrations specifically at 65 km/hr on your Yamaha FZX, there could be several potential causes. Here are a few possibilities:
Engine RPM Range: Certain engine configurations may have specific RPM ranges where vibrations are more pronounced. At 65 km/hr, your bike might be operating at a speed that corresponds to a particular engine RPM range, which could contribute to the vibrations.
Tire Condition and Balancing: Check the condition and balance of your tires. Worn or unbalanced tires can introduce vibrations, especially at higher speeds. Ensure that your tires are properly inflated and in good condition.
Maintenance: Regular maintenance is essential for a smooth and optimal riding experience. Ensure that your bike is well-maintained, with the engine and chassis components properly lubricated and adjusted.
Riding Style: Sometimes, the way you grip the handlebars or your body position can amplify vibrations. Experiment with your riding posture and hand grip to see if it makes a difference.
If the vibrations persist or are particularly concerning, it's advisable to have your bike inspected by a qualified mechanic. They can evaluate the specific cause of the vibrations and recommend appropriate solutions.
Remember that individual experiences with vibrations can vary, and what one rider perceives as notable vibration, another may find acceptable. If possible, try test riding another Yamaha FZX/FZ-S to see if the vibrations are similar or significantly different. This can provide a basis for comparison and help determine if the vibration you're experiencing is within the normal range for this model.
