Exhaust Yasuni R4 Derbi

The Yasuni R4 Exhaust Derbi / Aprilia / Gilera is a high-quality high-end system for tuned engines with considerably increased displacement (84 cc to 95 cc).

Clean welds and a high quality Max Pro aluminium silencer guarantee a great race look. Shape and volume of the expansion chamber are designed for maximum performance in the mid and high rpm range with a particularly wide power band. This means that the R4 already brings a lot of power at mid rpms and holds it well into the upper speed range.

The exhaust can be used with most 84cc - 94cc racing cylinders available on the market.

Because of the bigger volume we recommend you to use a bigger carburetor like the like a PWK 30, a larger reed valve and a reinforced clutch to avoid clutch slippage.

Fits Derbi Senda X-Treme, Aprilia SX, Gilera SMT...etc.
