Modifying the handlebars on a Royal Enfield Thunderbird can be a personalization choice to improve comfort or achieve a different aesthetic. Here's a general guide on how to modify the handlebars:
Determine the new handlebar style: Research and choose the handlebar style that best suits your preferences and riding needs. Common options include ape hangers, drag bars, tracker bars, or café racer-style clip-on bars.
Gather the necessary tools: You'll typically need a socket set, Allen wrenches, screwdrivers, and possibly a torque wrench, depending on the specific modifications you plan to make. It's always a good idea to consult the service manual for your Thunderbird model to ensure you have the correct tools and understand the process.
Disconnect and remove the existing handlebars: Start by disconnecting any cables and wires connected to the handlebars. This may include the throttle cable, clutch cable (if applicable), brake lines, and electrical connections. Loosen the bolts securing the handlebars to the triple tree or risers and remove the handlebars.
Install the new handlebars: Position the new handlebars on the triple tree or risers and align them as desired. Make sure they are securely fastened with the appropriate bolts and tighten them to the manufacturer's recommended torque specifications. Ensure that the handlebars are straight and aligned with the front wheel.
Reconnect cables and wires: Carefully reconnect all the cables and wires, ensuring they are properly routed and secured. Pay attention to the length and tension of the cables to ensure smooth operation.
Test the controls and adjust as needed: Before riding, check the functionality of all controls, including the throttle, clutch (if applicable), brake levers, and switches. Ensure they have proper clearance and operate smoothly. If adjustments are required, refer to the service manual for guidance.
Check for clearance and comfort: Sit on the motorcycle and check for any interference or discomfort caused by the new handlebars. Ensure that the handlebars don't hit the fuel tank, fairing, or any other components during full lock-to-lock turns. Make any necessary adjustments to achieve optimal clearance and comfort.
It's important to note that modifying your handlebars may have legal implications depending on your jurisdiction. Some regions have regulations on handlebar height and style. Before making any modifications, ensure that you are compliant with local laws and regulations.
If you are unsure about the process or lack experience with motorcycle modifications, it's advisable to seek assistance from a professional mechanic or authorized Royal Enfield service center to ensure the modification is done safely and correctly.
