Arrow 71915AKN Indy Race Dark Aluminium Homologated Silencer – BMW F 900 R and F 900 XR 2020-2024

The Arrow 71915AKN slip-on exhaust is from the Indy Race Carbon Cap line with a "Dark" aluminum finish and a carbon end cap, developed for BMW F 900 R and F 900 XR 2020-2024, including A2 versions (Arrow vehicle type 4R90 · 4R90R). The official diagram bears the EURO5, ECE, and CARB marks: it is approved for road use. Body length 250 mm, outlet 58 mm, db-killer included, declared weight 2.33 kg.

✓ Strengths

• "Dark" finish — black aluminum body: the total black look of the Indy Race range, with only the carbon end cap breaking it up
• EURO5 / ECE / CARB Approved — Arrow sound and look while remaining road legal and passing inspections
• Carbon rear end cap — the detail that gives the Carbon Cap series its name
• Stainless steel silencer interior — the hottest working part is not aluminum
• Db-killer included — standard, not an accessory to buy separately
• Welded frame attachment — integrated bracket in the body, no collar to position by eye
• Valid for four models — F 900 R, F 900 R A2, F 900 XR, F 900 XR A2

Technical specifications

Technical data from the SPECIFICATIONS panel of the official Arrow catalog (71915AKN sheet) and the mounting diagram for the same application.

Vehicle compatibility

⚠️ The F 900 R and F 900 XR from 2025 are a different application (vehicle type MR90 / MR90R) and use different Arrow codes: this exhaust is not suitable. Always verify year and model before ordering.

The Arrow system on this motorcycle — what's approved and what's not

Other finishes for the same application

All six finishes are ECE approved on the official diagram: the body and end cap material changes, not the approval. In stores, the Dark and natural aluminum cost the same.

Mounting and combinations

The official Arrow diagram pairs the slip-on with the 71729MI mid-pipe, which in turn mounts on both the Arrow 71730MI headers and the original BMW ones. Those who want the complete system add the 71730MI racing headers — on the diagram they are connected with a dashed arrow, meaning they are optional, and Arrow declares them usable even with the standard silencer. Professional installation by qualified personnel is recommended: the frame attachment is welded to the body and must be aligned before tightening.

Who it's perfect for

For those with an F 900 R or F 900 XR 2020-2024 looking for a total black look: on dark liveries, the Dark disappears into the bike, on light ones it creates contrast. Same approval, same measurements, and same carbon end cap as the natural aluminum 71915AK, and in stores the same price: the choice is purely aesthetic.

Frequently asked questions

What does "Dark" mean?
It's the finish: Arrow officially calls it "Indy-Race 'dark' aluminum end cap with carbon end cap". The body is made of black aluminum instead of natural aluminum. Everything else — measurements, internal materials, db-killer, approval — is identical to the 71915AK.

Is it approved for road use?
Yes. On the official Arrow diagram for this application, the 71915AKN is in the Indy Race Carbon Cap — ECE HOMOL. block, and the diagram header bears the EURO5, ECE, and CARB marks.

Does it also fit A2 versions?
Yes. Arrow explicitly lists F 900 R / F 900 R A2 and F 900 XR / F 900 XR A2 2020/2024, vehicle type 4R90 and 4R90R.

Is the 71729MI mid-pipe needed?
The Arrow mounting diagram pairs the slip-on with the 71729MI mid-pipe, sold separately. Please note: that mid-pipe is marked Racing by Arrow. If your goal is to remain road legal, please contact us before assembling the system and we will evaluate the configuration together.

Is the db-killer included?
Yes. Arrow declares the presence of the db-killer in the specifications for this code.

What material is it made of?
Body made of "Dark" aluminum, rear end cap made of carbon, silencer interior made of stainless steel. The frame attachment is welded to the body.

Is it suitable for the F 900 R or XR from 2025?
No. From 2025, BMW changes the application (Arrow vehicle type MR90 / MR90R) and the codes are different. This slip-on only covers 2020-2024.

Is it an original product?
Yes: Arrow Special Parts, code 71915AKN, EAN 8019799108608, sold by Moon Bike S.r.l., authorized dealer.
