Accessories vs. original

Loosen the screw and clamp – and you are holding the silencer of the BMW R 1200 GS in your hand. A replacement part can be installed in a matter of minutes. But is it worth using the accessory exhaust? Who offers more performance, who sounds best? Eight providers compete against the Munich original.

To the fanfares, Mr. Kapellmeister, a flourish: As nimble as with the BMW R 1200 GS we haven’t been able to carry out an exhaust test in recent years. Because replacing the rear silencer is usually only a matter of minutes and does not pose any major challenges even to laypeople working with the tool box. Above all, a clever flap construction in the outlet section makes the screwdriver action incredibly easy.

A look back: In the past, an electronically controlled exhaust flap that existed in the original had to be either completely dismantled or at least shut down on almost every test motorcycle. Only then could an accessory pot be attached. In the current BMW R 1200 GS, on the other hand, the exhaust flap is placed at the manifold outlet in front of the connecting pipe and remains in normal operation with every replacement silencer.

Parallels to the current car emissions scandal?

Of course, everyone flinches when they hear the word flap control – and of course parallels are quickly drawn to the current emissions scandal in cars. Of course, the first question that arises is whether such a construction is legal at all. Because the main purpose of the flap on motorcycles is to ensure that the legally relevant driving noises are complied with. These are currently still measured according to EU regulation 97/24 / EC, which will be replaced by UNECE-R 41 from next year.

So far, the driving noises have been measured when accelerating from 50 km / h in second and third gear over a distance of 20 meters. According to the law, the phonometer can record a maximum of 80 decibels on average from all passages. A really sharp figure when you consider that a stormy autumn day already touches your ears with the same number of phoning numbers. Even with many moderately powered motorcycles, a flap is therefore essential in order to achieve this value.

Principle very simple

The principle is very simple. To effectively contain the driving noise, a flap in the exhaust tract is closed via servomotors and cables from a speed of 50 km / h. Depending on the acceleration values, the flap is opened again from 70 km / h upwards – with the effect, of course, that the number of decibels increases accordingly. In contrast to the current emissions affair, the motorcycle systems we know are not designed for pure test bench runs. The flap works in any case – regardless of whether the bike is rolling through town at 50 or is being moved as part of a noise measurement.

This means that it is completely legal, according to experts from various testing organizations from TuV or Dekra, if they are entrusted with the homologation of the corresponding systems. The extent to which this will change from 2016 onwards is currently still speculative. This practice has long been a thorn in the side of noise opponents when it comes to tuning silencers: How can it be that the motorcycles only have to be so quiet in the measuring range, but the phon values ​​may explode before or after the legally stipulated limits? Which is why they have great hopes for the realignment of the noise measurement regulations. With the complex measuring process and additionally lowered decibel values, the aim is to make the currently common flap tuning – quiet only between 50 and 70 km / h – impossible. However, it remains to be seen whether this actually works.

Original unbeatable in terms of power and torque

So let’s first take a look at the current test situation. And in this a completely dramatic picture emerges. Because anyone who thinks that he has made nimble legs with the quick muffler change on his BMW R 1200 GS will rub his eyes in amazement. The bitter truth on the MOTORCYCLE test bench: Not an accessory exhaust reaches the peak values ​​in terms of power and torque that are delivered by the original.

Many at least deliver values ​​at series level, some others, on the other hand, have to give in. Up to five percent less peak performance. That is anything but what you would expect from an accessory pot. At least a weight advantage can still be achieved. Instead of the standard part equipped with reflection chambers, the accessory pots filled with insulating wool can save up to 50 percent mass. And of course the sound makes the music. It’s hard to describe. That’s why you hear the GS overture to the test in this video.

New noise limits from 2016


Eight silencers for the BMW R 1200 GS in the product test


Jorg Lohse

Stricter limit values ​​will apply from 2016. Whether that will continue to work with a mouth?

Track closures, noise symposia, environmental initiatives against motorcycle crashes. The biker scene is currently grappling with this situation. It will be exciting in a few weeks. The new noise guideline UNECE-R 41 should turn the tap off from 2016 onwards. From 80 dB (A), which is currently permitted as driving noise, then a maximum of 77 dB (A) – to be complied with, of course, only for new motorcycles.

As usual, older guys enjoy grandfathering. The previous measurement method will also change. Essentially, the sound level permitted according to the new regulation is calculated from various measurements with constant speed and full load acceleration. Experts from various testing organizations believe that the new method will undermine the previous practice of regulating noise using flap controls. However, such systems are not generally prohibited – only if they are activated via test cycle detection.

This is how MOTORRAD tests

Loud or quiet? Phonetically correct measurement aria on the MOTORRAD top test area.

At the regulars’ table, it is quickly clear what characterizes a good replacement silencer: It has to sound as bold as possible! Which is why this purely subjective impression is also answered in the test. Of course, it has no influence on the pure scoring. For this, only the hard facts are decisive, which are collected in the everyday MOTORRAD test routine. After the flying visit to the workshop (initial assembly) and photo studio, it’s off to the field tests.

The top test site at Neuhausen ob Eck airfield is ideal for checking compliance with the noise limits stipulated in EU regulation 97/24 / EC. The Dynojet test bench clarifies whether the boxer wins – or loses – punch with the accessory silencers.

Commentary Jorg Lohse (head of service)


Eight silencers for the BMW R 1200 GS in the product test

MOTORRAD service boss Jorg Lohse (46) has doubts about the new measuring method.

Gear weighting, reference acceleration, partial load factor …, phew: the new noise regulation UNECE-R 41 will regulate how loud motorcycles can be on almost 50 bureaucratically claused pages. The number 77 decibels hovers ominously above all – three less than before. Whereby the old and new limit values ​​are not comparable. What used to be measured at 80 dB (A) can suddenly be five decibels quieter with the new method – on paper! Which is why I also doubt that there will be more calm in the future with the new regulation. Even after 2016, there will still be motorcycles that are perceived as too loud by the environment. Because outside the measuring range, there is still no defined maximum value that must be adhered to.

Perhaps it would have been brave to finally sweep the established measurement method, which is also the basis of the new regulation, completely off the table. And to tackle a solution that really cuts noise peaks. On some racetracks it’s very simple: Maximum dB value at half the rated speed – if you are above it, you stop. Period. But then presumably a phone number would have been on the paper that would have led to an outcry among motorcycle opponents at round tables and in citizens’ groups: What, so loud? One thing is clear: noise harms us all. Which is why only the feeling in the right hand will really ensure peace.

The final evaluation at a glance.

Gone are the days when almost every accessory silencer was superior to the original part in many respects. Tuning by exhaust – that’s history. In the meantime, you have to be happy that the muffler alternative still achieves the series values ​​at all. In this test, only Akrapovic and BOS can maintain the performance level of the BMW R 1200 GS in the original setting. Mivv, Spark and Termignoni at least win on the scales – the latter also scores with convincing values ​​in the noise measurements. In the last column there are sometimes horrific prices. 700 euros and more for a simple muffler? That already seems heavily exaggerated.
