Just a little whine.
I like that the vibration is greatly improved, but I have some belt whine. Love the easy
intstlation and the quality of the tensioner.

Drive belt tensioner
Excellent product, easy to install (50 minutes or less) fast shipping well built, reduced vibration 95%

Much Better Than The Others
I had similar a product installed from another vendor, but it did nothing to stop the vibration. Big wast of money. Tried this product on a recommendation. Glad I did. This product has eliminated 95% of my vibration on my 2014 Spyder RTS.

Billet Aluminum Belt Tensioner
Easy to install haven’t driven it yet.

What a difference
Had mine installed by the dealership. Boy what a difference it’s so smooth, now not sure why I waited so long. Vibration virtually gone at all speeds.
