Exhaust Yasuni R2 carbon Kevlar® AM6 / Derbi

YASUNI R2

The Spanish brand was originally known in MotoGP, when two-strokes dominated the discipline, but has also built up an excellent reputation with high-quality exhausts for 50cc motorcycles, including the Yasuni R2.

PERFORMANCE YASUNI R2

The Yasuni R2 is powerful and high-torque, especially in the medium and high RPM range. It is primarily intended for 50cc to 70cc tuning cylinders (entry-level and racing).

To make optimum use of the power of the Yasuni R2, we recommend using a 19 - 24mm carburetor and a reinforced clutch to prevent slipping when starting the engine.

Not compatible with original cylinders!

The more power and displacement, the higher the number of the Yasuni R exhaust should be selected: Yasuni R1, R2, R3, R4...

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

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: 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.
