It is generally not recommended to increase the tire pressure beyond the manufacturer's recommended specifications. The recommended tire pressure is determined by the motorcycle manufacturer based on factors such as tire size, load capacity, riding dynamics, and overall performance.
In the case of the Honda Hornet 160R, the recommended rear tire pressure is typically around 29 PSI (pounds per square inch). Deviating significantly from this recommended pressure can have adverse effects on the motorcycle's handling, stability, and tire wear.
Increasing the rear tire pressure to 35 PSI, as you mentioned, may result in a harsher ride and reduced traction. It can also negatively impact the tire's contact patch with the road, potentially compromising grip and overall safety.
If you have specific concerns or preferences regarding tire pressure, it is advisable to consult the owner's manual of your Honda Hornet 160R or reach out to a Honda dealership or authorized service center. They can provide you with the most accurate guidance and recommendations based on your motorcycle's specifications.
