Description
High mount exhaust 80 - 90 Derbi
Stage6 developed a tuning exhaust specially developed for 50cc supermotos from Derbi, Aprilia and Gilera with 80cc and 90cc displacement.
Design Stage6 80-90 Derbi exhaust
The exhaust is a high mount model and consists of a handmade expansion chamber made of several sheet steel segments and a orange CNC silencer. Please note that the racing exhaust comes with a so-called racing finish, i.e. it is not painted or otherwise treated! We therefore recommend applying a lubricating spray regularly to prevent premature rusting.
With Stage6 R/T CNC silencer.
Performance high-mount exhaust for derbi
The high-end exhaust develops its full potential with 80cc / 90cc tuned engines; you can look forward to excellent performance over the entire rpm range, and especially at mid and high rpms your engine will turn into a rocket.
We recommend this exhaust for use with the 88cc Stage6 Big Racing cylinder or an 88 Italkit cylinder.

Exhaust scooter, moped, motorcycle
The exhaust has a major influence on the performance of scooters and mopeds. By replacing the original with a tuning exhaust, you can improve the gas flow and increase the engine power.
exhaust parts
- The headpipe or header is the connection between cylinder and exhaust, and an exhaust gasket provides the necessary seal. In street-legal systems, the headpipe is equipped with a legally required restriction. Some people remove this restrictor to increase power.
- The actual exhaust body or expansion chamber is connected to the header pipe. In a classic 2-stroke expansion chamber type exhaust, gas pressure waves are used to improve engine performance.
- At the end there us the silencer or muffler that discharges the exhaust gases and, with the help of damping wool, also reduces the noise generated by the vehicle.
Replacing the exhaust
As a general rule, please check if the exhausts fits BEFORE REMOVING THE RESTRICTOR, otherwise the exhaust cannot be returned.
For 2-stroke engines, various settings and components usually need to be adjusted when the original exhaust is replaced with a tuning version. These changes include:
- Adjusting the carburetor by replacing the main jet.
- Upgrading the clutch or replacing the clutch springs.
- For scooters, it may be necessary to reduce the weight of the variator weights.
Tuning Level: High End 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.
High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.
Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.
