Arrow 71915PR Pro-Race Titanium Homologated Silencer – BMW F 900 R and F 900 XR 2020-2024

The Arrow 71915PR exhaust slip-on is from the Pro-Race Titanium Cap line, made entirely of titanium—body, end cap, and silencer internals—developed for the BMW F 900 R and F 900 XR 2020-2024, including A2 versions (Arrow vehicle type 4R90 · 4R90R). The official diagram bears EURO5, ECE, and CARB marks: it is road legal. The body is 250 mm long, with a 68 mm outlet, db-killer included, and a declared weight of 1.22 kg.

✓ Key Features

• Titanium throughout the slip-on — body, rear end cap, and silencer internals are all titanium, not just the visible part
• 1.22 kg — the lowest weight among the six Arrow slip-ons available for the F 900 R and F 900 XR 2020-2024
• EURO5 / ECE / CARB approved — Arrow sound and look while remaining road legal and compliant for inspections
• 68 mm outlet — the most generous outlet section in the range for this motorcycle (Indy Race models stop at 58 mm)
• Db-killer included — supplied as standard, not an accessory to be purchased separately
• Welded frame attachment — bracket integrated into 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 (71915PR sheet) and the mounting diagram for the same application.

Vehicle Compatibility

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

The Arrow System for this Motorcycle — Who is Approved and Who is Not

The Six Finishes for the Same Application

All six finishes are ECE approved on the official Arrow diagram: the material, outlet section, and weight change, but not the homologation. On the three Indy Race models, the silencer internals are stainless steel; on the Pro-Race Steel Cap models, the entire slip-on is steel; the 71915PR is the only one entirely in titanium.

Mounting and Pairings

The official Arrow diagram pairs the slip-on with the 71729MI central link pipe, which in turn mounts to both the Arrow 71730MI headers and the original BMW headers. Those who want the full system add the 71730MI racing headers—on the diagram, they are connected with a dashed arrow, meaning they are optional, and Arrow states they can be used even with the stock silencer. Professional installation 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 the lightest homologated slip-on in the range, with the tapered line and conical outlet of the Pro-Race instead of the squared tail of the Indy Race. Natural titanium remains light and darkens over time near the outlet weld; this is normal material behavior, not a defect.

Frequently Asked Questions

What is the difference between Pro-Race and Indy Race?
The construction differs. The Pro-Race 71915PR is entirely titanium—body, end cap, and silencer internals—with a 68 mm outlet and a weight of 1.22 kg. Indy Race models have a carbon end cap, stainless steel internals, a 58 mm outlet, and weigh from 1.90 to 2.33 kg. Body length (250 mm), inlet (49 mm), db-killer, and ECE homologation are the same for all.

Is it road legal?
Yes. On the official Arrow diagram for this application, the 71915PR is in the Pro-Race Titanium 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 types 4R90 and 4R90R.

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

Is the db-killer included?
Yes. Arrow states the db-killer is present in the specifications for this code.

What material is it made of?
Of titanium, for all three components Arrow specifies: body, rear end cap, and silencer internals. The frame attachment is welded to the body. It is the only one of the six slip-ons for this application to be entirely made of titanium.

How much does it weigh?
Arrow declares 1.22 kg. This is the lowest value among the six slip-ons available for this motorcycle: 710 grams less than the 71915PK, which is titanium but with a carbon end cap and stainless steel internals.

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.
