It is generally recommended to stick to the manufacturer's recommended tire size for your motorcycle. The Apache RTR 200 4V BS4 model is typically equipped with a 130/70-17 rear tire.
While it may be possible to replace the tire with a slightly wider one, such as a 140/70-17, there are a few things to consider before making the change:
Clearance: Ensure that the wider tire will have enough clearance within the motorcycle's swingarm, chain, and other components. Check the available space to avoid any interference or rubbing issues.
Handling and Performance: Altering the tire size can affect the motorcycle's handling and performance characteristics. A wider tire may impact the bike's agility and responsiveness, especially in terms of cornering and maneuverability. It's important to keep this in mind when making any modifications.
Speedometer Accuracy: Changing the tire size may also affect the accuracy of the speedometer and odometer readings. A wider tire can result in a slightly different rotational speed compared to the stock tire, potentially leading to discrepancies in speed and distance measurements.
Considering these factors, it is generally advisable to consult with a professional mechanic or a representative from the tire manufacturer to determine if a tire size change is suitable for your specific motorcycle model. They can provide more precise guidance based on your bike's specifications and any potential implications of altering the tire size.
