Who it's perfect for

For those who use the BMW C 650 Sport every day and want to remove the bulky and heavy original silencer, without breaking the law. The Race-Tech is a 350 mm "Dark" painted aluminum body with a carbon end cap, weighs 2.79 kg, comes with a db-killer and has ECE marking on the Arrow diagram: it changes the tail's line and sound while remaining a street-legal part. It must be chosen together with the link pipe: with the approved catalytic 73009KZ, the system remains compliant with Arrow's specifications for road use.

Frequently asked questions

Is the Arrow 73512AKN approved?
Yes. The official Arrow diagram for the BMW C 650 Sport 2016-2020 marks this code as ECE HOMOL.: the exhaust is approved for road use and does not compromise inspections, provided the db-killer is kept in place.

Do I also need to buy the link pipe?
Yes. The 73512AKN is the muffler only: on the Arrow assembly diagram, it connects to a link pipe, and the two link pipes available for this scooter are the approved catalytic 73009KZ and the racing 73009MI. Without one of these, the exhaust cannot be mounted.

What is the difference between the 73009KZ and 73009MI link pipes?
On the Arrow diagram, the 73009KZ is the "approved catalytic link pipe" and bears the homologation mark; the 73009MI is the "racing link pipe" and does not have that mark. Both, says Arrow, also fit on original headers.

What material is it made of and how much does it weigh?
The body is aluminum with a "Dark" finish, meaning dark painted; the rear end cap is carbon fiber and the internal parts of the silencer are stainless steel. The weight declared by Arrow for this code is 2.79 kg. The frame attachment is via a welded bracket.

What are the dimensions of the exhaust?
Arrow declares a body length of 350 mm, with an inlet diameter of 60 mm and an outlet diameter of 50 mm. There is no provision for a lambda sensor or CO sensor, which remain upstream of the exhaust on the C 650 Sport.

How much does it change compared to the original?
Arrow publishes for its system on the C 650 Sport 51 HP and 56.39 Nm compared to the 46 HP and 52.96 Nm of the standard system, with 4.41 kg less weight and 2 dB more noise (93 dB versus 91 at 3,750 rpm). These values refer to the complete system, exhaust plus link pipe.
