The SIMONINI 'left' as it is called internally - is a very nice to drive exhaust for almost all tuning cylinders with small stroke (50-112ccm). A galvanized manifold, which is connected to the exhaust body by springs, as well as a removable muffler are trademarks of this exhaust, which is unfortunately only available for the PK 50.
However, as with almost all systems offered especially for the PK, it is possible to use it on other frames with slight modifications to the exhaust and/or chassis.
The Simonini pleases with a wide speed range which provides a good power in every situation, especially on high capacity cylinders.
A not too loud exhaust, but due to its unconventional design it is not exactly an inconspicuous system. The muffler looks evil (parallel to the chassis), under the left side cover and makes it clear to everyone that this is not mommy's shopping scooter.
