How long does the Factory Belt Tensioner last by miles?

[Dakotaz]

We have a 2021 RT with 15,275 miles and a 2023 RTL with 8409 miles and I was wondering if anyone has had experience with how long the factory belt tensioner last by miles. Obviously, it seems to last to 15,000 or maybe I'm just lucky on that one. Going on a trip and wondering if I should replace one or both based on current mileage.

Has anyone used Lamonster's replacement roller on the factory tensioner?

Thanks for any input or suggestions.

My 2023 RTL factory belt tensioner started making noise around 14k miles so I removed it. The bearing was totally shot. For me I have not noticed any difference with or without it, but I know I don't want the tensioner to destroy the belt while out on a ryde, hence I removed it.

Just put the 2023 on the hoist to check it out and saw the pulley with a groove in it. Didn't see anything on the belt to cause it.

I think I am going to remove the one on my Arizona Spyder RT (first owner put it on it) when I get back to this Fall. I have the same worry banging around in my head. The Washington Spyder does not have one and there's no noises coming from the belt. I put an aftermarket one on the first Champaign Spyder (now gone) because of belt noise between 45-50 MPH.

Almost every time, I fueled up, I'd reach under there and check the slack in the bearing. I finally got some after 3K miles. I carry zip ties with me, so I zip-tied it up off the belt and later removed it completely. A failing cheap bearing doesn't come close to the cost of a belt replacement.

I just replaced mine at 40,000 miles. The spring had broken quite awhile earlier. Before installing new one I checked my belt tension.,170lbs. Just right for me.
