On January 1, 2025, the new regulation comes into force that will have to do with the standards that will be required of new motorcycles. This is what is known as Regulation R41.05, which is part of what we know as Euro5+.
The Euro5+ is the final part of the package of new Euro5 measures that motorcycles had to comply with in terms of all types of regulations, among which emissions and pollution had a lot of weight.
Precisely this point is what is addressed by Euro5+ and the new regulation, which is responsible for going one step further in noise pollution (in addition to gas emissions conditions). It is not that the noise limits have changed and are more strict as of January 1, 2025, but that they will be measured differently to ensure that laboratory tests agree with reality.
The bottom line is to tackle noise in urban centers and rural areas, and hence the tests are different. To simplify the explanation of the previous rule, manufacturers were previously required that the noise made by the motorcycle when moving at 50 kilometers per hour was the same as that which the motorcycle made with the engine off.
Being such an open regulation, it allowed manufacturers to find a way to comply with this requirement since it did not specify gears or other details that could make passing the test easier.
The new regulation also seeks a certain homogeneity
But what changes now is that the tests will be measured with the motorcycle at specific revolutions and in a range of acceleration speeds, with speeds that will vary depending on its power. This, in itself, makes it much more fine-tuned in terms of noise. But the measurements will also be made in all gears if the motorcycle is compatible.
Basically, what this homologation implies is that the motorcycles will have to be measured in a very different way from what was done previously, increasing the measurements made.
Now independent organizations will be in charge of approvals, recording the results of the tests. Previously, it was the manufacturers who recorded the results and, later, the independent body was the one who randomly tested a unit of the model to verify it and determine the accuracy of the report, something that the EU considered as leaving too much room.
In any case, the reality is that practically all manufacturers have advanced the work and many of the motorcycles, which are in dealerships today, are already prepared for the new regulation and Euro5+.
