Since 2006, Yasuni fabricated its new exhaust named "R" on the market.
Again, they succeeded in revolutionizing the market with products at unbeatable performance, quality and price.
To meet the request of various world championships, they have developed 3 types of fumes.
The Yasuni R1 agrees very well with 50cc engines where R2 fits perfectly with 70cc!
The Carerra R3 is really the exhaust for the engine high end.
!!! Aprouved on the road !!!
