The Chrome expansion is made of variable thickness steel sheet. This feature provides greater protection in the most exposed parts to damage and maintains a good sound to the exhaust system. 

• The outer coating in nickel + chrome, guarantees a great resistance to weathering
• Optimized development to reduce bulk and keep the expansion pipe very close around the engine.
• For the Enduro version the expansion softens the engine output without penalizing the maximum power.
• Compatible with the original silencer.
