I'd noticed a very loud harmonic whine at around 42-45 mph on my 2016 ST-S that I thought was maybe from the front left wheel. It hadn't occurred to me that this was from the belt.

Mentioned it to the service manager when I brought it in the other day for the 600 mile service and he said this was a common problem and recommended the BRP vibration damper. I said that I had seem some things online about this and about some vendor products I had seen (here) and he again "strongly" recommended in favor of the BRP...and against alternatives!
I can't even find this on the BRP site!!!!

I've searched thru a bunch of threads and it seems the main negative against the BRP product vs other vendor products is the durability and longevity. I've also read about top vs bottom mounts.

So...any thoughts?
