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.
