The LeoVince GP One Slip-On exhaust is designed for the Triumph Speed 400 and Scrambler 400 X. Before starting any work, ensure the exhaust system has cooled down completely to prevent burns or damage to heat-sensitive components like fairings or hoses. Professional installation is highly recommended.
Note: During the first kilometers of use, the exhaust system will undergo a break-in period. It is normal to observe slight gas leakage or white smoke during the first use, even after the engine is turned off. Check the tightness of all fasteners after approximately 100 km.

Maintenance
Periodically check all brackets and fasteners, as they may be affected by heat and vibration. Replace worn components such as sound-deadening material, seals, or rubber parts as needed. For cleaning, use gasoline, diesel oil, or alcohol. Do not use any solvents. Discoloration of the silencer is normal due to heat and material properties. Any modification or tampering with the silencer is strictly prohibited and voids the warranty.
