Stage6 Exhaust Flange R1200 / R1400 Piaggio

Stage6 R1400 Racing exhaust

The R1400 exhaust has been on the market for many years and has established itself over time as the reference in the high-end sector. It has been modernized with the MK2 version to adapt to the new cylinders on the market.

Features R1400

• Made by hand in Italy
• Classic expansion chamber exhaust made from thin sheet steel
• Carbon silencer
• Untreated racing finish
• Volume and shape perfectly suited for high-end racing 70 cc cylinders

Tip: As it is not painted, we recommend oiling the 2-stroke exhaust regularly to prevent premature rusting.

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!

Tuning Level: Racing

We categorize our products into different performance levels  Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.

Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
