When choosing brake pads for your Triumph Bonneville, you'll need to decide between organic and metallic options. Metallic brake pads are made from metal shavings and bonding agents, while organic brake pads use Kevlar, carbon fiber, or other materials.   Organic brake pads tend to be quieter and produce less dust, while metallic brake pads provide better durability and stopping power. Ultimately, the best brake pad for your needs will depend on your driving habits and preferences.    If you do a lot of city driving, organic brake pads may be the way to go. However, if you frequently take your Bonneville out on the open road, metallic brake pads may be the best choice.
