To enhance the racing soul of your Yamaha YZF R9, Spark has developed an exhaust system that redefines the motorbike's performance standards, making it the ultimate solution for optimizing the power delivery of the Japanese three-cylinder supersport.
Spark has developed a full titanium system, the result of cutting-edge technology and directly engineered by the R&D department, which collaborates in the world's top racing championships.
The same technology used by official teams in the WSSP600 is now available for your R9, with FIM approval for use in the WSSP Championship.
The result is an engineering masterpiece that combines lightness and power: with a 49% weight reduction compared to the stock system, it ensures a significant increase in torque across the entire rev range, turning every corner into pure adrenaline.
The Force Evo silencer represents the excellence in materials, technical details, and design: its titanium structure, characterised by elegant ribbing, seamlessly integrates with the carbon fiber end cap.
The silencer's volume ensures effective decibel control, to comply with increasingly strict regulations on European circuits.
Technical specifications:
GYA8801T (configuration without db killer): 102 dB at 5000 rpm
GYA8801T (configuration without db killer): 103 dB at 6000 rpm
This system has been specifically developed for motorbikes in Supersport configuration (designed for installation with a Supersport chassis, not compatible with passenger footpegs and equipped with 4 carburetion plugs: one on each cylinder connector and one after the 3-in-1 section).
Additionally, the GYA8802T version is available, maintaining the same lengths and diameters as the WSSP600 version while delivering the same performance benefits. However, it allows installation on the bike in its original configuration (with stock swingarm, radiator, passenger footpegs, and two ports for the original lambda sensors).
The system stands out with the Konix Evo silencer, embodying the true racing essence and representing the latest evolution of Spark design. The harmonious combination of the conical titanium casing and the carbon fiber end cap, with sharp-edged elements, gives the motorbike a unique and distinctive character.
