When choosing a silencer for your Royal Enfield Thunderbird, it ultimately depends on your preferences and the specific characteristics you are looking for. Both Khalidaro, Red Rooster Performance, and Wild Boar are aftermarket silencer manufacturers known for producing high-quality silencers for Royal Enfield motorcycles. Each brand may offer different designs, materials, and sound profiles.
It's important to consider factors such as local regulations regarding noise levels, your personal taste in sound, and the performance impact. Keep in mind that altering the stock silencer may void the manufacturer's warranty, and you should also check if any modifications comply with local laws and regulations.
To make the best choice, it is recommended to read reviews, seek recommendations from experienced Royal Enfield owners or enthusiasts, and even listen to sound samples or visit local motorcycle accessory stores to hear the different options in person. This way, you can assess which silencer aligns with your preferences in terms of aesthetics, sound, and overall performance.
