Participation Bos Exhausts on Motorrad BoxerCup 2020

Bos Exhausts, Vos Oss and Wilbers Suspension closely work together to participate in the prestigious Motorrad BoxerCup 2020. The Bos Exhausts team had high expectations of the coming races untill now… Unfortunately it is not certain due to the ‘Corona crisis’ whether the upcoming races can take place as planned. As soon as there is news about the BoxerCup or race schedule we will share it on this website and of course on our Facebook page. To be continued!

In the meanwhile we were present at the Motor fair Dortmund that took place in March. Alongside we show you some nice pictures of our exhibition stand.

Because your new
BMW R1250GS only deserves
the best!

This impressive BMW R1250GS and Adventure can master any surface. But it gets even more exciting with the new Euro 4 approved Bos DesertFox EVO exhaust! Including heat shield, titanium connection pipe and eye catching black scratch protector, this exhaust system will satisfy your every wish!

The DesertFox EVO Black Coated or Carbon Steel exhaust system is also available for the BMW R1250GS HP and HP Adventure (HP Scratch protector and mouting flange in blue). Don’t hesitate, order now and experience the difference!

The facts behind the Euro 4 standard for motorcycles

All new models of 125 cc and up must comply with the Euro 4 regulations as of the 1st of January 2016. For existing Euro 3 models manufacturers have two options: either they adjust the model in question before the 1st of January 2017 to create a Euro 4 model or they catalogue the individual model as a predictive model and they have until the 31st of December 2018 to sell their stock -under certain conditions-.

This means that the dynamic noise must be reduced by Euro 4 with a few dB (A). Your Euro 3 muffler was allowed to make up to 80 dB (A), this is now reduced to 77 dB (A).

The well-known (removable) Db-eaters are not allowed anymore. A Db-eater must be permanently attached now, so that you have to seriously damage your exhaust to remove the Db-eater. The widely used excuse to the police: “Sorry, my Db-eater was really installed and must have fallen during the ride!” is no longer possible!

And then, the electronically controlled valves. This may be used, provided that they always work properly and are not installed with a ‘test cycle’ recognition. Electronics can recognize a ‘test cycle’ and then switch to a special program in which the valve closes and thus is suddenly much quieter. In the media, this software has become known as the ‘tamper software’.

For us as an exhaust manufacturer any new standard means a new set of challenges. Besides all modifications to produce a beautiful and better sounding exhaust, inspections have become more complicated and a costly procedure. Each new exhaust undergoes a rigorous and extensive sound test on special asphalt, before any (type) approval is given.

And perhaps you did not know it yet. As of 2020 the even stricter Euro 5 standard for all motor vehicles will be introduced.
