Description YASUNI R Tuning ExhaustScooter exhaust Yasuni R for Minarelli vertical, this version with black silencer.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 avoid vibrations, the stainless steel mount is double rubber mounted, and does its job really well.in order for the YASUNI R to be street-legal, the headpipe and silencer are equipped with restrictors. If run with the original cylinder, performance is similar to the original exhaust, only with a throatier sound. When removing the restrictors, the exhaust loses road approval, but can unfold its full potential.Conclusion:The YASUNI R has a very wide power band and is really quiet, but with a very throaty sound. The silencer can be replaced to visually adapt the exhaust to your scooter. As with expensive racing systems, the mufflers are spring-loaded, which makes leaking virtually impossible.To get the most out of this exhaust you should use it with a 17,5mm carburetor (minimum) and a tuning CVT.Technical data:Material body: sheet steelMaterial bracket: stainless steelMaterial silencer: ALUColour silencer: blackWith road approval / homologation / E-passFor Minarelli vertical (Yamaha Slider, BWs etc.) Questions about the product Downloads and Media Data sheetInstallation guide
