Your ride back
Dr. Jekill & Mr. Hyde has created an electronically adjustable exhaust system for Triumph Motorcycles that gives you the opportunity to adjust your sound to the moment and choose a sound mode for every situation. At the push of a button. Be eloquent and silent if you wish or be heard when the situation asks for it.
Dr. Jekill & Mr. Hyde has the exhaust system for three different Triumph EURO-4 models: the Bonneville Bobber, Bonneville Speedmaster and Speed Twin, which all will be available soon. Other models and EURO-5 motorcycles will follow.
Our exhaust systems embody three unique sound modes: the Dr. Jekill mode, the Dynamic mode and the Mr. Hyde mode. By a simple push of a button on the handlebars a valve inside the muffler closes, opens or opens halfway, which gives the rider the possibility to easily adjust the sound to the moment. This makes it possible to be silent when the situation requires it, or be heard when it's appropriate. Our exhaust systems are 100% street legal in all modes: all systems have an European type approval and thus comply with all European laws and regulations, as well as being CARB/EPA and TÜV tested.
