Although bike enthusiasts are always looking for the latest exterior accessories to transform a mundane piece of metal into a truly moving piece of art, the main part that stirs imagination is under the hood. Being at the heart of your bike, the engine is the essence of power, torque, and speed. It’s all about the way it feels, the way it rides, and is what defines the character of your bike. Depending on what sits under the hood, you can count on your motorcycle to bring as much power as you need to zip around the city, venture through the wilderness, or blow the competition away at the track.
