Vibration
This is a very nice looking tensioner it will not stop all the belt vibrations but I would say it will kill roughly 90% of it which makes for a lot better comfortable ride on the Spyder RT the only way I know to get rid of all of it is Can-Am should have designed it with a drive shaft but since we have a belt this is one of the best things you should do really helps a lot

SpyderExtras Billet Aluminum Belt Tensioner / Idler for the Can-Am Spyder RT
VERY NICE , GOOD LOOKING . HEAVY ENOUGH TO GET THE JOB DONE . HOWEVER I HAVE NOT INSTALLED IT , YET . WAITING TO OIL CHANGE, TO DO IT .

Stop the flap
Product does what it should, stop that vibration at 70 MPH on freeway. Easy install, looks to be a well made item that should last. Idler wheel could be slightly larger, has room between gas tank, turn slower to have bearings last longer would be my suggestion.

Easy to stall
Spyder Billet Tensioner was very easy to install - especially watching the install video on Youtube. I was concerned I didn't place it perfectly aligned but realized that there is some give left to right and the friction of the belt will center it naturally. The best thing is no more shaking under load - perfect. I took it on a 500-mile treck and never shook once. I am depending on it to be a premium quality because it could damage my belt if the Tensioner failed.
