Oxa Hard Enduro Edition Silencer - Beta RR 250 2013-2025

Yes, the Oxa Hard Enduro Edition Silencer is designed for Beta RR 250 models manufactured between 2013 and 2025, so it will fit your 2015 model.

It is highly recommended to rejet your carburetor or remap your ECU after installing this silencer. This ensures optimal performance, prevents potential engine damage, and achieves the desired power delivery characteristics.

This silencer is compliant with FIM dB noise regulations for off-road competition use. It is not intended or certified for use on public roads.

The Oxa Hard Enduro Edition Silencer offers greater noise reduction than many other models, designed to meet FIM dB noise regulations for off-road events.

The primary advantage is its focus on improving low-end torque and providing a smooth, controllable power delivery at low to mid-range RPMs, which is critical for tackling technical Hard Enduro sections.

It's advisable to inspect the silencer packing annually or after significant off-road use, especially if you notice a decline in performance or an increase in noise. Refer to the product manual for specific repacking instructions.

This is often due to incorrect fuel mixture or ignition timing. Re-jetting the carburetor or re-mapping the ECU according to the bike's specific needs with the new silencer is likely required.

Check for air leaks in the exhaust system, particularly at the header and silencer connections. Adjusting the fuel mixture might also resolve this. Ensure the silencer packing is adequate.

Ensure the engine is running within its optimal temperature range. Overheating can be a sign of lean fuel mixture or inadequate cooling. Check for proper exhaust flow.

Verify that all connections are tight and sealed. Ensure the internal packing material is intact and sufficient. While designed for noise reduction, performance modifications can sometimes alter sound characteristics.
