Exhaust system from YASUNI as the larger and more powerful brother of the "Scooter Z" for sporty automatic setups.
As the big brother of the "Scooter Z", this exhaust system is slightly larger and more powerful in all areas. It is particularly suitable as a good addition for 70cc sports and mid-race Cylinders and is aimed at setups in which the peripherals are also adapted accordingly. The spring-loaded suspension, the large manifold diameter and the design with Cone and counter Cone underline the sporty character. Depending on the version, the system is available with carbon polyamide or aluminum dampers and usually has an E-pass. It is made of steel and clearly designed for performance-oriented combinations with a matching Cylinder and Carburettor.
SIP-TIP:
Lightweight Vario rollers, harder Clutch Springs, 17.5 mm Carburettor, long gear ratio and a SPORT Racing Cylinder are ideal for this exhaust system.
