Performance declared by Arrow

The 2.60 kg declared as the weight of the Arrow system corresponds to the weight of this exhaust, which is the only one provided for the motorcycle. Arrow also publishes a Dynojet graph, which you can find among the photos: the maximum power increases from 89.74 HP with the original exhaust to 91.75 HP with only the Arrow exhaust, and reaches 94.34 HP in the full system configuration.

Who it's perfect for

For those who have a BMW F 800 R between 2009 and 2016 and want to remove the original silencer without replacing the entire system and without breaking the law. The dark body with the carbon end cap looks good on the naked bike, the link pipe and db-killer are already included, and the motorcycle loses 2.3 kg on the right side. However, those who travel with original BMW side cases should know that this exhaust is not compatible with them.

Frequently Asked Questions

Is the Arrow 71746AKN road legal?
Yes. On the official Arrow mounting diagram, the code appears under the homologation mark, in the table of exhausts for original headers. It can be used on the road and presented for inspection, provided the db-killer remains in place.

Does it work with original BMW side cases?
No. The Arrow diagram shows an explicit warning next to this code: the exhaust does not fit with original BMW side cases. If you use the stock side cases, you must forgo either this exhaust or the cases: the two are not compatible on the same motorcycle.

Which BMWs does it fit?

Do I also need to change the headers?
No. In the Arrow diagram, the exhaust is classified among exhausts for original headers and the stainless steel link pipe is already included: it mounts on the stock system without additional purchases.

Arrow declares a 400 mm long body with a 112 × 140 mm section, an inlet diameter of 54 mm, and an outlet of 50 mm, weighing 2.6 kg. It is fixed to the frame with a steel clamp. There is no provision for either a lambda sensor or a CO sensor.

How much does it change compared to the original?
