Has anyone tried one of these?

And if so what were the results?

 

I've never hear of it. That said, I'm not say'n that it's not a good thing.

 

+2 on never hearing of this item.

 

Nope never heard of it.

 

I had never heard of it before today either.

FWIW I just looked in the '13 Road King manual and the stock chain tensioner looks a lot like the one in the link.

 

Well, somebody buy it and let us know how well it works!

 

Everyone that has them raves about them and everyone that doesn't have them say they are an unnecessary toy.
Thought about them myself, but there are other things I want more.

 

I have an M6 that makes similar claims and certainly makes gear changes more pleasant, but yet another 'never heard of it'! I'd like to know in what way it is hydraulic.

 

It looks like theres a shock instead of a spring for tension.

 

Not hydraulic, but HD has an automatic tensioner that I believe comes on newer bikes but does work on our Evos.
