X-Racing Round Color Line Slip-On Rear Muffler Beta RR 125, model year 25 and later (Euro 5+), red, with carbon end cap, with EC type approval

The X-Racing ATR-05 is a slip-on rear silencer designed for Beta RR 125 models that meet the Euro 5+ emissions standard. It replaces the stock silencer and reduces weight while delivering a sportier exhaust note. The housing features a red powder-coated finish and is paired with a carbon fiber end cap.

The system is compatible with the original exhaust manifold and is mounted at the original mounting points. The removable DB killer allows operation within the scope of the existing registration. Without the DB killer, the exhaust system no longer complies with regulations for public road use.

As mileage increases, the sound-deadening material inside a rear muffler may lose its effectiveness. Typical signs include a louder exhaust noise or a change in the sound profile. Damage from crashes, rust, or cracks may also necessitate replacement.
