Yes, it is possible to change the rear tire of a Royal Enfield Standard 350 to the rear tire of a Royal Enfield Classic 350. The Standard 350 and Classic 350 models share many components and have a similar frame and wheelbase, so the rear tire sizes are generally compatible.
Compare the tire sizes of both models and confirm that the Classic 350's rear tire will fit without clearance issues.
Speedometer calibration: Changing the rear tire size can affect the accuracy of the speedometer reading. A larger or smaller tire diameter can lead to a discrepancy in speedometer readings. It's advisable to consult with a knowledgeable mechanic or a Royal Enfield dealership to address any potential speedometer calibration issues that may arise.
Suspension adjustment: Switching to a different rear tire size might affect the suspension setup and overall handling characteristics of the motorcycle. It's recommended to consult with a professional or a Royal Enfield service center to ensure that the suspension is appropriately adjusted to accommodate the new tire size.
Legal considerations: In some countries or regions, modifying the tire size of a motorcycle may have legal implications. It's essential to familiarize yourself with the local laws and regulations regarding modifications to ensure compliance and avoid any legal issues.
Before proceeding with any modifications, it's always best to consult with a qualified mechanic or a Royal Enfield authorized service center. They will have the expertise and knowledge to guide you through the process and ensure that the modification is safe and appropriate for your specific motorcycle model.
