The mode in between Dr. Jekill and Mr. Hyde. Close to a stock exhaust but much more distinct.
Listen and enjoy the three different sound modes of the Dr. Jekill & Mr. Hyde - The Exhaust.
Dynamic Mode - A tamed Mr. Hyde sound.
Dr. Jekill Mode - A calm, low-key but distinctive sound.
Dr. Jekill & Mr. Hyde's sound engineers have used the character of the engine as a guideline in all sound modes. We are sincerely proud of the sound and product that Dr. Jekill & Mr. Hyde have created. The power of the engine is perfectly transmitted to the rumbling sound coming out of the Dr. Jekill & Mr. Hyde Exhaust.
When you start your bike the valve is always closed. When you push the button on your handlebars once, the valve will open up completely and your exhaust is set in the performance mode. Click it again and the valve fully closes again. When you double click the button, the valve will be opened to 50% and you ride in the dynamic mode*.
* Blackbox systems (motorcycles without CAN bus) offer two sound modes.
