Description
doppler am6 exhaust reducer Ring
Doppler offers this reducer flange for 50cc motorcycles with Minarelli AM6 engine.
The bushing has an outer diameter of 28mm and thus allows the installation of exhausts with a 28mm inner diameter plug connection.
This bushing is used with exhausts from Yasuni, Polini, Voca and Tecnigas.
Bushing dimensions: Cylinder side 25mm outside / Exhaust side 28mm outside
ATTENTION: It is important to note that Doppler offers two reducer bushes with similar dimensions. In this case, the diameter of 28 mm refers to the outer diameter of the bushing. If you need a bushing with an inner diameter of 28mm, you will find it under CGN502151.
Exhaust flange
The exhaust flange provides a stable, sealed and separable connection between the exhaust and the engine.
Function of the exhaust flange
Depending on the engine type, the exhaust flange is attached to the cylinder by means of bolts or by press-fitting. It is then fitted into the exhaust pipe and held in position by two exhaust springs, thus maintaining a certain flexibility. To ensure tightness, there is normally an exhaust gasket. Thus, the flange provides a secure and at the same time flexible connection between the cylinder and the exhaust.
And what is an exhaust restrictor?
Many 50cc scooters and motorcycles are factory equipped with an exhaust / manifold restrictor. This restriction reduces the diameter of the exhaust flange, which restricts the performance of the exhaust. This restriction was introduced to comply with noise emission regulations and to limit the speed of 50cc scooters and motorcycles.
Many riders remove this restriction to improve the performance of their two-wheeler. However, the gain in power then leads to the loss of the homologation, so beware!
