Belt Tensioner included on new 2021 Spyder F3-S Special Series

Just noticed this morning that the f3 came with the tensioner installed. Will ask dealer later if they installed it post delivery from factory.

That would be some thing I would keep a eye on, EVERY oil change!!! Just my 2 cents!!

My 2020 F3-S SS also came with one. I thought it was an option and never really looked deep down there to see it. It failed at about 10,000 miles and scored the belt pretty badly.
My dealer got me a replacement belt and dampener under warranty and I replaced them myself. I've subsequently removed the dampener completely so I never have to worry about it again. The belt vibrations are only minimally annoying to me, I'd rather have the peace of mind not wondering when it's going to fail again.

Me? I would take it off and chuck it in the weeds. Just one more thing to fail and leave me stranded. Playing with the belt tension can get the vibs to disappear or at least to a reasonable level.

Hm. Now I am wondering if my 21 base F3 has the tensioner. It did come with the white sprocket.

***Just checked. No tensioner but have the updated white sprocket. ***

From the fiche @ Partshark. If you do have the #350 one, double check the two mounting bolts #350a. The Loctite coating on them is so thick they take loads of torque to completely tighten down snug to the frame as needed.
