The new Tecnigas GP4 means not only sharper exhaust optics à la Superbike but also a solid sound experience!Worth mentioning is the construction of this system specifically made for 4-stroke scooters: it improves the engine's performance and at the same time ensures a sharp visual appearance due to its design!Often original systems from the manufacturer are very expensive to obtain, and poor spare parts supply is not uncommon...Thanks to the upgraded surface of the Tecnigas system, you no longer need to worry about rust. And for your wallet, it also provides some relief compared to an original system!Approval: E-approval.
