Euro4: when a new era asks for new exhaust solutions, we are ready!

2017 marks the start of the Euro4 era, which comes with stricter regulations in terms of emission and sound. Thanks to extensive work from our in-house research and development department our exhaust systems are fully up to the Euro4 requirements, which means everyone can still enjoy the silent comfort of Dr. Jekill and the deep dark rumble of Mr. Hyde now and in the future. We will briefly explain the consequences of Euro4 and how we made our products ready for this new legislation.

What did we change for the Euro4 models?

  • New improved riding modes
  • A more environmental friendly exhaust system
  • The most advanced electronically adjustable exhaust system
  • Introducing our new “Smart Valve System”
  • Increase in performance in Dynamic and Performance Mode

What did not change?

The silence of Dr. Jekill & dark Mr. Hyde rumble available at the touch of a button.

Dr. Jekill & Mr. Hyde vs. Euro4: The key points

Performance icon small

Performance: staying ahead of the game
Performance is of importance, also in the Euro4 era. Our Euro4 approved exhaust systems offer an increase of performance in both Dynamic and Performance mode.

Design product icon small
Design: customize and recognize

The possibility to choose and combine different designs and end cap variations remains for most of our systems, allowing Dr. Jekill & Mr. Hyde customers to configure their exhaust according to their taste in style. New for our Euro4 models is our revised type shield which includes our logo. This will mark the beginning of the Euro4 era, and it will make our products even more recognizable.

Sound icon small
Sound: Dr. Jekill & Mr. Hyde

New regulations don’t take away our passion for sound, which means all Euro4 motorcycles equipped with a Dr. Jekill & Mr. Hyde exhaust system are guaranteed to have the characteristic deep dark Mr. Hyde rumble in Performance mode, a slightly toned down sound in Dynamic mode, and the option to ride silent when switching to Travel mode. All modes are available at the touch of a button.

Environment small
Environment: ride green and sound mean

The Euro4 norm brings stricter emission standards to the table, which means we had to engineer a greener exhaust system. At Dr. Jekill & Mr. Hyde we highly value a clean environment, which is why we have developed our new electronically adjustable exhaust systems to meet the emission standards of the Euro4 legislation without compromising on sound.

Smart Valve System
The valve reacts “smart and legal” at certain gears, speeds or Rpm thus always complying with the legislation that Euro4 has sprung upon us.

Intelligent internals: our brand new Smart Valve System

Valve closed
Travel Mode: valve closed

Dr. Jekill, the social sound. When the valve is closed you will experience a calm sound, perfect for travelling and long distance touring. This mode adds comfort to your ride and to blend in silently in your environment whenever you prefer.

Valve opened 100%
Performance Mode: valve fully opened

The deep and dark Mr. Hyde rumble we are famous for. This mode completes your total riding experience and offers you a sound which is unheard of for any stock exhaust system. This mode offers you the best sound and the highest level of performance.

Valve opened 50%
Dynamic Mode: valve half opened

The Dynamic mode will bring your sound between being Dr. Jekill and being Mr. Hyde. This mode brings your sound level close to that of the stock exhaust, albeit with a more pronounced tone and improved performance.
