SITOPLUS, for 2-stroke engines, is an exhaust system line for the best-selling motorcycles and scooters in Europe that, while looking like those originally fitted, are completely re-designed inside and guarantee that the engines will perform better, especially at low to medium revs.

The final result is a clear improvement in torque and acceleration.

All in compliance with legal requirements, which makes SITOPLUS a "special" product but regularly approved.
