Arrow 77502PR Pro-Race Titanium Silencer – BMW F 900 R / XR 2025-2026

The Arrow 77502PR silencer is a slip-on from the Pro-Race line with a titanium body: the short, conical "trumpet" shape derived from racing, the most compact of Arrow's homologated range for this motorcycle. The inside of the silencer is also titanium; the stainless steel link pipe is integrated into the silencer and not sold separately. For BMW F 900 R, F 900 XR, F 900 R A2, and F 900 XR A2 from 2025 and 2026. Homologated: the Arrow fitting scheme is marked ECE HOMOL. with EURO5+, EC ECE, and CARB markings.

✓ Strengths

• Titanium body and interior – the lightest and most heat-resistant material in the range
• Pro-Race line – short, trumpet-shaped silencer, the most compact among Arrow's homologated options for the F 900
• Road legal – EURO5+ · EC ECE · CARB: the motorcycle remains compliant, with documentation included in the package
• Integrated stainless steel link pipe – mounts to the original headers, no other components needed
• Compatible with center stand – explicitly stated in the Arrow fitting scheme
• Removable db-killer included – removes for track use and reinstalls for road use
• No sensors to relocate – Arrow states this silencer has no lambda sensor bung and no CO sensor bung

Technical specifications

Arrow does not publish the weight for this code, and the body length, inlet diameter, and outlet diameter are 0.00 in its datasheet: therefore, we do not report them.

Vehicle compatibility

Source: Arrow application sheets 1966 (F 900 R / F 900 XR 2025/2026) and 2037 (F 900 R A2 / F 900 XR A2 2025/2026). Always verify your motorcycle's model and year before purchasing.

Other finishes for this motorcycle

• 77502PK – Indy Race EVO titanium with carbon end cap – same material, longer body, and carbon end cap
• 77502AK – Indy Race EVO aluminum with carbon end cap
• 77502AKN – Indy Race EVO dark aluminum with carbon end cap

Perfect for whom

For those who own a BMW F 900 R or F 900 XR from 2025 or 2026 – including the A2 restricted version – and want the shortest and lightest homologated Arrow silencer, with the racing look of the Pro-Race trumpet shape. Compared to the Indy Race EVO, the silencer shape changes, not the homologation or the mounting method: original headers, center stand in place, sensors staying put.

Frequently asked questions

Is the 77502PR silencer homologated?
Yes. The Arrow fitting scheme is marked ECE HOMOL., with EURO5+, EC ECE, and CARB markings at the top: by installing it, the motorcycle remains road legal. Keep the documentation found in the package.

Which BMW models does it fit?
On the F 900 R and F 900 XR from 2025 and 2026, including the A2 restricted versions. Arrow treats them on two pages, vehicle type MR90 for full power versions and MR90R for A2, and on both it indicates the same code 77502PR.

Is the link pipe included or sold separately?
It is included. Among the official specifications for this Arrow code, the link pipe material is declared as stainless steel: the connection pipe is part of the silencer. The diagram specifies that these are silencers for original headers, so no other components are needed.

What material is the end cap?
The two official Arrow sources do not agree: the fitting scheme classifies this code in the "PRO-RACE TITANIUM END CAP" group, while the technical sheet on the same site indicates "stainless steel". We prefer to tell you both rather than choosing one: the body and interior of the silencer are titanium in both readings.

What is the difference with the Indy Race EVO 77502PK?
The shape and length of the silencer change: the Pro-Race is the short, conical trumpet, the Indy Race EVO is longer and has a carbon end cap. The body is titanium on both, as are the homologation, welded mount, db-killer, and integrated stainless steel link pipe.

Do I have to remove the center stand?
No. The Arrow fitting scheme explicitly states that these silencers mount with the original center stand.

Do the lambda sensors need to be moved to the silencer?
No. Arrow states this silencer has no lambda sensor bung and no CO sensor bung: the motorcycle's two sensors – the diagram indicates that this BMW has two – remain where they are on the original system.

Will it fit my 2022 F 900 R?
No. The F 900 R and XR from 2020 to 2024 are a different application, vehicle type 4R90 and 4R90R: the Pro-Race titanium for those years is 71915PR. This code only covers 2025 and 2026.
