Exhaust -SITO- GY6 (4-stroke) 50cc (139QMA/B) 12 inch wheels

The name SITO is synonymous with high-quality replica exhaust systems at fair prices. Visually, they resemble the original exhaust systems. However, the inner values are optimised for the benefit of better performance. The systems develop more torque in the lower and medium speed range, the scooter accelerates more powerfully and achieves a higher top speed.

Please note:
retrofit systems usually always have more power than the original exhaust. In order to obtain approval, they are throttled at the factory, which may result in a shift in the power band.
In order for the scooter to reach its full power and speed, it may therefore be necessary to adapt the engine to the new exhaust with different variator weights and/or clutch springs, even if it is to be used throttled on a standard engine.

Attention! Only with modification suitable for Euro4 models
