Product Overview

Safety Precautions
Before beginning any installation work, ensure the motorcycle's exhaust system has cooled completely to prevent burns or damage to heat-sensitive components such as fairings, hoses, or rubber sleeves. We strongly recommend that the installation be performed by a qualified professional.
Installation Instructions


- Remove the original stock silencer.
- Clean and inspect all mating surfaces to ensure they are in good condition.
- Mount the provided spacers, washers, and brackets as indicated in the technical drawings.
- Fit the clamp onto the LeoVince pipe and connect it to the original collector.
- Partially tighten the securing straps to allow for final alignment adjustments.
- Install the LeoVince muffler and secure all fasteners.
- Connect the provided springs or clamps.
- Verify correct alignment and tighten all bolts securely.
- Start the engine, allow it to reach operating temperature, and check for any gas leaks.
Maintenance and Care
Regularly inspect all brackets and fasteners, as they may be affected by vibration and heat. Periodically replace consumable parts such as sound-deadening material, seals, and rubber components. For cleaning, use gasoline, diesel oil, or alcohol; never use aggressive solvents. Note that some discoloration of the silencer is normal due to heat and material properties. Any modification or tampering with the exhaust system is strictly prohibited and will void the warranty.
Important Notes
During the first few kilometers of use, the exhaust system will undergo a break-in period, which may result in minor gas leakage. After approximately 100 km, it is essential to re-check and tighten all fasteners. It is also normal for some white smoke to appear during the initial use, even after the engine has been turned off.
