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

The X-Racing AT-05 is a slip-on rear muffler designed for Beta RR 125 models that meet the Euro 5+ emissions standard. It replaces the stock muffler and offers a sportier look and a lighter design compared to many original systems. The body is made of aluminum and is paired with a carbon fiber end cap.

Compared to the stock rear silencer, the X-Racing AT-05 delivers a more powerful and sportier exhaust note without altering the characteristic single-cylinder sound. At the same time, the combination of the aluminum shell and carbon fiber end cap gives the rear of the vehicle a high-quality look. Thanks to its lighter construction, the weight of the exhaust system is also reduced compared to the original.

This design is compatible with the original manifold and is mounted using the existing mounting points. The removable DB killer allows operation in accordance with the respective registration. Without the DB killer installed, the exhaust system no longer complies with regulations for public road use.
