Yasuni R1 exhaust system for Minarelli AM6 engines, Available with a black silencer.
28mm manifold (25mm reducer included).
Yasuni TUB903TB
The R2 exhaust has a bigger outlet diameter then the R1. The R2 is 28mm and the R1 is 25mm. The R2 exhaust would be better if you were planing on fitting a big bore kit in the future.
They are not restricted from the factory which means they are not E-marked (too highly tuned).
As soon as we get new stock for Yasuni R1 Exhaust- Aprilia RS50/ AM6, we'll send you an email.
