Perfect for

It is the right part for those who are installing an Arrow system on their BMW R nineT, Scrambler, or Urban GS and have decided to eliminate the stock exhaust valve: in place of the valve body, a section of stainless steel pipe with the same 63 mm connections remains, so the line closes without makeshift adapters.

Frequently asked questions

What is the Arrow 11001MI for?
It replaces the original exhaust valve in the central section of the system: in its place remains a stainless steel pipe with 63 mm connections. It is used when, by installing an Arrow system on the R nineT, you choose to remove the stock valve instead of keeping it in place.

Which motorcycles does it fit?
On the BMW R nineT from 2014 to 2019, on the R nineT Scrambler from 2016 to 2020, and on the R nineT Urban GS from 2017 to 2020. These are the three applications provided by the Arrow catalog for this code: outside these years, the correct spare part is different.

Is it mandatory to install the Arrow exhaust?
No. On the R nineT family, Arrow collectors can also be installed while maintaining the original exhaust valve, as indicated in the manufacturer's assembly diagram. The 11001MI is only for those who decide to remove the valve and need to close the exhaust line.

What material is it made of and how much does it weigh?
It is made of stainless steel, the same material as the Arrow collectors for the R nineT range. It is a polished pipe with two circumferential ribs, with an inlet and outlet diameter of 63 mm and a weight of approximately half a kilo, 0.5 kg.

Does it have lambda probe connections?
No: the element has neither a lambda probe connection nor a CO sampling hole, and does not include a db killer. It is a pure pipe section, designed only to take the place of the valve body between the header and the system collector.

Is it a genuine Arrow product?
Yes. It is the Arrow Special Parts catalog item with code 11001MI and EAN 8019799057241, new and never installed. Moon Bike S.r.l. is based in Cercola, in the province of Naples, and ships it from Italy with invoice and manufacturer's warranty.
