Shipping notice: truck drivers' strike in Italy
Updated 19/10/2026
Since 16 October, truck drivers protesting against high diesel prices have been blocking roads and ports in Southern Italy (Campania, Calabria, Sicily, Puglia, Basilicata), and the protest could spread to the rest of the country. The strike affects all our shipments, in Italy and abroad: Poste Italiane is currently not collecting parcels, while BRT and DHL are collecting as usual but deliveries may be delayed in some areas.
- Italy we ship with BRT and DHL · possible delivery delays
- European Union for now we ship with DHL only · possible delays
- Non-EU countries (customs) shipments temporarily suspended: they will leave as soon as Poste Italiane resumes collections
We apologise for any inconvenience and thank you for your patience.

The Arrow 73009MI link pipe is the racing central section made of stainless steel for the Arrow exhaust system on the BMW C 650 Sport maxi-scooter from 2016 to 2020. It connects the headers to the Race-Tech silencer, also fits original headers, has a 50 mm inlet and a 60 mm outlet, and weighs 0.5 kg. It is not street legal: it is the track version. Product code 73009MI.
✓ Strengths
- Declared stainless steel – the Arrow technical sheet for this code states link pipe material: stainless steel.
- Measurements match the silencer – the 60 mm outlet corresponds to the 60 mm inlet of the Race-Tech 73512AKN silencer: the two parts are designed to couple.
- Also fits original headers – Arrow explicitly states this at the bottom of the model's assembly diagram.
- Or with Arrow headers – on the diagram, the link pipe is also connected to the 73010MI racing headers.
- Only 0.5 kg – this is the weight declared by Arrow for this code.
- Spring attachment – the part has a hook welded to the body for the retaining spring.

⚠️ Important notes:
• Not street legal. On the Arrow diagram, the 73009MI is the "racing link pipe" and does not bear the homologation mark, which appears next to the catalytic 73009KZ: this part is intended for track use, not for public road circulation.
• The link pipe alone does not make a system. It replaces the central section and, on the diagram, connects to the Race-Tech 73512AKN silencer, which must be purchased separately.
• Also fits original headers — this is the note Arrow explicitly states on the assembly diagram. Alternatively, it pairs with Arrow racing headers 73010MI.
• Arrow does not state the body length: on the technical sheet for this code, that field is zero, so you won't find it written here. Inlet and outlet are stated, however.
• Installation by qualified personnel is recommended.

Products listed in the catalog
- 73512AKN – the Race-Tech "Dark" aluminum silencer with carbon end cap, ECE approved, to which this link pipe connects
- 73009KZ – the approved catalytic link pipe, the street version of this part
- 73010MI – the racing headers, to complete the system upstream
Who it's perfect for
For those who take their C 650 Sport to the track and want the Arrow system in its most open configuration. This is the crossroads of the system: at the same point, Arrow offers two link pipes, and this is the racing one, without an homologation mark, while the 73009KZ is the street catalytic one. It's inexpensive, weighs half a kilo, and also mounts on stock headers, making it the part that allows you to try the Arrow system without replacing everything. Those who use the scooter on the street should opt for the 73009KZ instead.

Frequently Asked Questions
Is the Arrow 73009MI street legal?
No. On the official Arrow diagram for the BMW C 650 Sport 2016-2020, this code is indicated as a "racing link pipe" and does not bear the homologation mark, which appears next to the 73009KZ catalytic link pipe. It is therefore a part for track use.
What is the difference from the 73009KZ?
They occupy the same position in the system and have the same weight, but the 73009KZ is the approved catalytic link pipe, with the homologation mark next to the code on the diagram, while the 73009MI is the racing link pipe and does not have that mark. Both also fit original headers.
Does it fit original headers?
Yes. Arrow explicitly states this at the bottom of the model's assembly diagram: the 73009MI and 73009KZ link pipes also fit original headers. Therefore, you do not need to replace the headers to use this link pipe.
Which silencer does it pair with?
With the Arrow silencer for the same motorcycle: on the assembly diagram, the link pipe is connected to the 73512AKN, the Race-Tech "Dark" aluminum with carbon end cap. The link pipe's outlet is 60 mm and the silencer's inlet is 60 mm: the two measurements match. The silencer must be purchased separately.
What are its measurements and material?
Arrow declares the link pipe to be made of stainless steel, with a 50 mm inlet diameter and a 60 mm outlet diameter, weighing 0.5 kg. The body length, however, is not declared: on the technical sheet, that field is zero. There is no provision for a lambda sensor or CO sensor.
What changes in performance?
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 stock system, with 4.41 kg less weight and 2 dB more noise (93 dB vs. 91 dB at 3,750 rpm). These are values for the complete system, not just the link pipe.
