Description
The Arrow 72653AKN is an Indy Race EVO slip-on silencer made for the BMW F900GS and F900GS Adventure (2024-onward). The silencer body is built from dark-finish aluminium and is fitted with a carbon fibre end cap, giving it a modern, purposeful appearance. Its narrow oval body shape draws inspiration from the oval racetracks of Formula Indy racing, and the design has been reworked to include an indent on the side that both enhances the look and adds robustness and rigidity to the silencer. Inside, the silencer uses stainless steel internal components, and the connecting mid-pipe, or link pipe, is also made of stainless steel for durability. A welded mount is provided for secure and straightforward installation onto the motorcycle. The silencer is supplied with a removable dB killer, allowing the rider to manage the exhaust note. According to the listing, this version carries European and Swiss EURO 5 approval, meaning it is homologated for road use in those markets. The exhaust is made entirely in Italy. As a slip-on, it replaces the original silencer while retaining the bike’s standard collector and catalytic section.
