Euro 5+ for motorcycles – everything you need to know at a glance
From 2025, the Euro 5+ standard will be mandatory for motorcycles. This further development builds on the Euro 5 requirements introduced in 2020 and brings stricter rules for emissions monitoring and the durability of systems such as catalytic converters. The objective: fewer emissions in the long term and more sustainable use of technology. But how exactly do these changes affect us drivers? What are the requirements and what should you prepare for? Here are the most important facts and background.
Euro 5+ – Why an extension of the existing standard?
The evolution from Euro 4 to Euro 5 and now to Euro 5+
Since 1999, the EU has been pursuing the goal of reducing pollutant emissions from vehicles with the so-called Euro standards. For motorcycles, Euro 4 (from 2016) was a major turning point with significantly stricter limits for nitrogen oxides (NOx) and carbon monoxide (CO). Euro 5, introduced in 2020, continued these requirements, with even stricter limits for all types of emissions.
Euro 5+ goes one step further: instead of just limiting emissions, the technology is questioned. Do emissions control systems really last the entire lifespan of a motorcycle? How can you ensure that the limit values are also adhered to in real driving operations?
This is where Euro 5+ comes in – with stricter testing procedures and expanded monitoring of emissions-related systems.
The Sabina test robot from Dr. Jekill & Mr. Hyde simulates driving conditions for exhaust systems.
The three central innovations in Euro 5+
1. Onboard Diagnostics II (OBD II)
Motorcycles must be equipped with a more advanced onboard diagnostic system that continuously monitors the function of emissions-related components. This means that problems such as a defective catalytic converter can be identified early. The driver is informed of malfunctions before higher emissions occur.
2. Long-term durability of exhaust gas purification systems
Manufacturers must prove that catalytic converters and other emissions-related components function throughout the entire lifespan of a motorcycle - not just on the test bench, but also in real driving conditions.
3. More realistic noise testing
The limit values for driving noise remain at 77 dB(A), but the test methods are adjusted so that they better reflect real driving situations. The aim is to ensure that motorcycles remain quiet in everyday life - without losing the character of a bike.
What does Euro 5+ mean specifically for motorcyclists?
Purchasing decisions – what awaits you?
• New purchases: Motorcycles that are newly registered from 2025 must meet the Euro 5+ standard. For us drivers, this means more modern technology, but also potentially higher acquisition costs.
• Existing vehicles: Models registered before 2025 are not affected by the new regulations. So you can continue to drive your current motorcycle without restrictions.
Technology and maintenance – what changes
The more advanced exhaust systems and the new OBD II could ensure that maintenance becomes more precise, but also more complex. Repair costs could increase, especially if there are defects in catalytic converters or sensors. Positive: Such problems are detected early by the diagnostic system, which can prevent consequential damage.

Dr. Jekill & Mr. Hyde – Innovation meets new norms
A good example of how manufacturers react to emissions regulations is Dr. Jekill & Mr Hyde. They are known for their electronically adjustable exhaust systems, which both meet legal requirements and maintain driving pleasure.
For Euro 5, for example, they have developed an O₂ sensor extender that sits between the body and the end cap of the system and continuously monitors the exhaust gas values. This ensures that regulations are met without losing the typical sound.
It is to be expected that they will again develop solutions for Euro 5+, or have even already developed them. At the European Bike Week, Dr. Jekill & Mr. Hyde first insights into their new approaches to how modern exhaust systems can meet the stricter requirements without compromising on quality or driving experience. Technologies were presented that not only meet the strict requirements of the Euro 5+ standard, but also simulate real driving operations to ensure maximum reliability and efficiency.
Euro 5+ for motorcycles simply explained 75
What was particularly impressive was the use of their Sabina test robot, which recreates driving operations under realistic conditions in order to test the systems for longevity and efficiency. At the same time, the company emphasized that they do not lose sight of the needs of their customers - especially those who continue to expect the characteristic sound and special driving experience of a Harley-Davidson.
This balance between legal requirements and drivers' expectations impressively shows how technological innovation and the preservation of tradition can go hand in hand.
Sabina test robot – realistic testing of exhaust systems.
What does the future hold – the outlook for Euro 6
Euro 5+ is not the end of development. There are already discussions about the introduction of Euro 6, which may come in 2028. This could lead to further tightening of emissions and driving noise. There are also topics such as the electrification of motorcycles and safety requirements (e.g. ABS requirement for light motorcycles).
For us drivers the question remains: What is the balance between driving pleasure and regulation? It is clear that the coming years will be exciting – both from a technical perspective and for the market.
Summary: What you need to know now
• Euro 5+ applies to all new registrations from 2025.
The standard expands the existing Euro 5 requirements with more stringent testing and monitoring.
• Existing vehicles are not affected.
You can continue to ride your current motorcycle as usual.
New vehicles without Euro 5+
New vehicles without Euro 5+ should be registered in 2024, if at all it will be very time-consuming to get your vehicle registered. The authorized dealers will have to work with daily registrations. There are limited exceptions for manufacturers when carrying inventory into the new year. The rules are different here; if the manufacturer itself carries out a daily registration, according to my information, the vehicle is still considered a new vehicle for the current year. It will also be possible to buy a Sport Glide, for example, in 2025. Contrary to previous information, there will still be Sport Glide and Fat Bob models in 2025.
• The new systems offer advantages, but also bring challenges.
Advanced exhaust technology ensures cleaner values and lower emissions, but could make maintenance more complex.
• The future remains in motion.
Euro 6 and electrification could further change the market. Anyone planning a new motorcycle should keep an eye on developments.
Harleysite. Compiled to the best of our knowledge. This is a very complex topic and despite careful research, errors cannot be ruled out.
Almost everyone who thinks of Harley-Davidson thinks of the unmistakable sound of these machines. And although many love this sound more than anything else in the world, every few years it becomes more difficult for the motorcyclist to enjoy this sound.
Jekill and Hyde Street Glide Sharkskin Blue
With new rules and regulations, the best thing we can do is cruise along the highway quietly like a mouse without our beloved blubber as a suitable soundtrack.
Valve exhaust manufacturer Dr. Jekill & Mr. Hyde offers the solution to thousands of drivers with their electronically adjustable exhaust systems, giving drivers the optimal sound without the risk of ending up on the wrong side of the law.
But with new agreements like R41.05 and Euro5+, the voices are getting louder and louder that flap exhaust systems are now over... but is that really the case?
Euro5+ and R41.05 - what does that mean?
First the facts: What do the new regulations mean? Of course there are pages full of technical language written about it, but we'll summarize it briefly. Euro5+ is the current regulation for emissions controls and requires vehicles to meet strict criteria for harmful emissions. These provisions are essential to reduce environmental impacts and promote a more sustainable future; Criteria already outlined by Dr. Jekill & Mr. Hyde are fulfilled.
R41.05 is different because it concerns the noise regulation of motorcycles and is intended to reduce noise pollution. These regulations require that motorcycles remain below a certain decibel level at speeds between 10 and 100 km/h. These regulations apply to new motorcycles in the EU, as well as to previously registered motorcycles that are newly registered.
Dr. Jekill & Mr. Hyde offers the solution to stricter legislation
In order to write a program under these conditions that still offers the driver the ideal sound and is legal, a system must go through countless test runs and drives in order to perfectly match the software to the exhaust system. In short: it is almost impossible for a human being made of flesh and blood to achieve this.
Introducing Sabrina
To ensure that the new Dr. To ensure that Jekill & Mr. Hyde systems comply with R41.05 regulations, the exhaust manufacturer, headquartered in the Netherlands, has invested in a state-of-the-art testing laboratory. In a closed room with several microphones and the latest sound software, all bikes and their exhaust systems are tested and checked to the utmost.
The new CVO 121 Street Glide in the Jekill & Hyde test laboratory.
At the center of this testing process is a robot named Sabrina. It continuously carries out emission and sound measurements as well as endurance tests under the highest precision conditions. Thanks to it, a revolutionary flap system could be developed that adapts to driving behavior to maintain the optimal sound level and offer a constant sound experience within legal limits.
VIDEO - MEET SABRINA THE TEST ROBOT - Dr. JEKILL & Mr HYDE
For this purpose, a completely new Smartbox (the brain of a Dr. Jekill & Mr. Hyde system) was developed, as well as servomotors that react at lightning speed. Since the software now has to intervene more often, this should not be perceived as a nuisance for the driver. Thanks to the new actuators, the flap can now be positioned in many more positions than before, so the ride still feels very 'smooth'.
Without these testing facilities and technologies, it would be virtually impossible to develop a legal exhaust that both meets R41.05 standards and offers a high quality sound experience. Therefore, Dr. Jekill & Mr. Hyde is the only manufacturer of adjustable exhaust systems in the world that can provide the optimal sound through this combination of advanced technology, robotics and state-of-the-art testing infrastructure.

Thanks to the new technology and Sabrina, it's Dr. Jekill & Mr. Hyde managed to create a perfectly fitting exhaust for the new HD CVO 121 models. Which is of course legal and, despite new strict rules, still offers the driver the ultimate driving experience.
This technology is of course also used for all other new models such as the 117 Tourer, Sportster S and Nightster, making Dr. Jekill & Mr. Hyde more than ready for the future. So if you thought it was the end of the flap exhaust... you thought wrong!
