The Bajaj Pulsar 150cc UG4.5 typically comes equipped with a rear tire size of 100/90 R17. The tire size you mentioned, 130/70 R17, has a wider width and a lower profile compared to the stock tire.
While it is technically possible to fit a 130/70 R17 rear tire on a Pulsar 150cc UG4.5, there are a few factors you need to consider before doing so:
Wheel Clearance: You need to ensure that the wider tire will fit within the available space on the rear wheel. Check the clearance between the tire and swingarm, chain, and other components to ensure there is enough room for the larger tire.
Handling and Performance: Altering the tire size can have an impact on the handling and performance of the motorcycle. A wider tire can affect the bike's agility, cornering ability, and overall balance. It may also have an impact on acceleration and fuel efficiency.
Speedometer Accuracy: Changing the tire size can affect the accuracy of the speedometer reading. A larger tire circumference can result in an overestimation of the motorcycle's speed. You may need to recalibrate the speedometer or use an external speedometer to ensure accurate readings.
Legal Considerations: Modifying the tire size may have legal implications, depending on the regulations in your country or region. Make sure to check local laws and regulations regarding modifications to motorcycles.
It is recommended to consult with a professional mechanic or an authorized Bajaj service center to get expert advice specific to your motorcycle model. They can assess the feasibility and provide guidance on the potential implications of fitting a larger tire size on your Pulsar 150cc UG4.5.
