Euro 3 to Euro 4, what’s the deal?

With the launch of our new Euro 4 model; the Herald Maverick, we thought we would clear up any questions on exactly what changes are in Euro 4 compared to its predecessor, the Euro 3 range.

The Euro directives give specifications on the build and efficiency of new vehicles registered within any of the EU states, covering everything from the mirrors and noise to the emissions and brakes.

The main difference between Euro 3 and Euro 4 is that the amount of pollutants allowed has been greatly reduced utilising Electronic Fuel Injection (EFI), and that all bikes must now have Combined or Automatic braking systems (CBS/ABS).

New bikes will also include on board diagnostics which will measure and record the status of the bikes emissions management systems and fault-finding and status updates for service technicians. It also has a guarantee from the manufacturers that it will still perform at the same level for 20,000km. Most of the changes won’t be so obvious when you’re sat on your Herald but you might notice that you’re spending a bit less on fuel because the engine will now be more efficient.

Key stats on the difference between Euro 3 and Euro 4 bikes as previously mentioned will include on-board diagnostics and a durability test of 20,000km. When it comes to emissions, the Carbon Monoxide (CO) on Euro 4 motorbikes are 1.14g/km as opposed to its Euro 3 predecessor or of 2.0g/km whilst Nitrogen Oxide (NOx) is also reduced.

A final test carried out is the SHED test (Sealed Housing for Evaporative Determination) where the bikes are stored in a container and are measured based on the fumes they emit.
