In terms of performance, the Yasuni R lies between the Yasuni Z and the Yasuni C16 – an all-rounder with excellent performance over a very wide power band. Ideally suited for 50cc and 70cc sports & mid-race and racing cylinders; definitely the go-to muffler for 70cc tuning.
To exploit its full potential, we recommend combining it with a 17.5mm carburetor (minimum) and a tuning CVT.
