Retrofit silencer

For the mighty muffler of the big bandit there are plenty of cheap alternatives on the accessory market. MOTORRAD tested 13 aluminum and stainless steel pots for retrofitting.

Large-displacement motorcycles usually only pass the legal noise regulations if they are equipped with silencers that work according to the reflection principle and are therefore correspondingly voluminous. At least the vehicle manufacturers seem to be of this opinion. The Suzuki Bandit 1250 / S is a case in point. The manufacturers of retrofit systems, on the other hand, usually rely on absorption dampers, which can be much slimmer due to their design and are therefore popular with many bandit owners as a prettier alternative. Another reason for the willingness to convert is the poor sound of the series system. In the opinion of their owners, powerful motorcycles can also sound powerful – ideally within the legal framework. This is supposed to be guaranteed by the EC operating permit (EG-BE), which is only given silencers whose exhaust and noise values ​​are in accordance with the law. The fact that accessory silencers are usually much lighter than the original exhaust and often cost significantly less also makes them interesting.

MOTORRAD invited 13 inexpensive retrofit models in aluminum and stainless steel to a large comparison test. All candidates manage without a catalytic converter, as this is in the Bandit’s collector under the engine and is not affected by the conversion. The test criteria include the following:

Processing (10 points):

Unclean weld seams, protruding, sharp-edged clamps or end tubes that have not been deburred are quality defects and will be punished with point deductions.

Fit / assembly (15 points):

How easy is it to assemble the silencers? Is the accuracy of fit on the pipe transitions and on the brackets correct? Do you have to assemble a lot of small parts or do a few simple steps suffice for the attachment? How many tools do you need? Few manufacturers include self-explanatory assembly instructions. The one-piece Shark-Conic muffler can be installed particularly quickly and easily. The whole thing is much more difficult with the Ixil, where the lower strut mount has to be dismantled for the supplied main stand stop.

Weight (15 points):

Every kilogram saved improves the bandit’s power-to-weight ratio. Although every gram doesn’t really count with the 1250, a lightweight muffler has never harmed a motorcycle. All tested accessory pots are between two and four kilograms lighter than the 6.5-kilogram series.

Top performance (30 points):

How well does the test system stand in the feed? Does the accessory pot even lose valuable horsepower compared to the series? Increases in output of 20 hp as with the 1200 bandit models, which in the 1990s were still throttled to 98 hp via the exhaust, are no longer possible by adding a retrofit damper to the Bandit 1250. With more than six HP more power than the standard system, the Leovince muffler is ahead in this rating. Adding the GPR and Ixil models leads to a loss of around ten horsepower.

Performance development (30 points):

A harmonious, even development of power and torque without serious drops over the entire speed range brings plus points.
Stationary and driving noise: MOTORRAD checked the noise values ​​in cooperation with the specialists from the Dekra Technology Center (see box on page 101). It was found that only a few of the tested accessory silencers comply with the legally relevant driving noise limit values. That is why not all candidates receive a MOTORRAD verdict in this test. This is confirmed by the Bandit developers, who have given the large-displacement machine a very voluminous reflective muffler. It may not look nice, but it easily complies with the applicable noise limits.

Performance and noise measurements: numbers, data, facts


Product test retrofit silencer for Suzuki Bandit 1250-S


Hertneck

Driving noise measurements with radar monitoring; Stationary noise measurement with speed control device; Performance measurement on the roller dynamometer.

As with previous exhaust tests, the MOTORRAD editorial team received active support from the experts at the Dekra Technology Center in Klettwitz, which is located around 50 kilometers north of Dresden right next to the Lausitzring. There you will not only find the most modern performance and engine test benches, but also an extensive area for test drives of all kinds.

Performance measurement:
All candidates flexed their muscles on the Dekra roller test bench. Engine power and torque were recorded over the entire speed range. The respective maximum values ​​are listed in the table at the bottom right. The curves that are also included in the scoring can be found in the associated data boxes.

Standing noise measurement:
For checks during traffic checks by the police, the tolerance limit is up to 5 dB (A) more than entered in the papers. The Bandit paper value is 84 dB (A), the tolerance limit is 89 dB (A). But even if the limit is not exceeded, the law enforcement officers can withhold the vehicle for an all-important driving noise measurement in the event of justified doubts, because only this is considered authoritative before the law. When measuring stationary noise, the microphone is positioned at the level of the exhaust outlet at an angle of 45 degrees to the vehicle’s longitudinal axis and at a distance of 0.5 meters. The measurement takes place at a standstill at half the nominal speed – with the Bandit, which develops its maximum output at 7500 rpm, thus at 3750 rpm. The result is the highest of three measured values, rounded to full dB (A). The result is astonishing: some of the accessory dampers don’t even make the tolerance limit.

Driving noise measurement:
It takes place on a large area with normal asphalt. There must be no sound-reflecting objects within 50 meters of the measuring section (see photo above). During the recording, the motorcycle drives in second and third gears at a constant 50 km / h (plus / minus one km / h tolerance) towards the measuring section and then accelerates fully by suddenly pulling the gas. In each of the two gear steps, two passages from the right and two from the left are recorded. The total of eight measured values ​​are rounded and then a 1 dB (A) tolerance is deducted. The mean value of this gives the official driving noise value.


Vehicle requirements:
The test motorcycle for homologation or re-measurements of accessory silencers with a series system may exceed the driving noise value entered in the papers – for the Bandit 1250 this is 78 dB (A) – by a maximum of 3 dB (A), but the valid limit value of 80 dB (A) only by 1 dB (A). Thus, the Bandit should reach a maximum of 81 dB (A).

MOTORRAD allows the test facilities this generous tolerance limit. And yet more than half of the candidates are in some cases significantly higher. The roaring loud Hashiru pot kills the bird with 88 dB (A) driving noise.

Final scoring

BILLION

Conclusion:

The driving noise limit breaks the neck of many a hopeful candidate. If you put one of these pots in a control device that is clearly too loud, you shouldn’t be surprised if your bike is withdrawn from traffic – despite EG-BE. Only six participants will receive a MOTORRAD judgment. Laser grabs the test victory, the cheap Hurric receives the buy tip. Even Holeshot in fourth place gets a “very good”, and for the overweight series system it’s enough for one “Good”. Due to the comparatively complex assembly and significant performance losses, there’s for the Ixil “sufficient”.
