Simple design, haven't tried my bike with it on yet, but it can't over tighten so I should get the response that you should expect.
Good performance - rough appearance

I like the Hayden M6 tensioners and run them in several bikes.
Very rough low quality machining on the parts but they are still quite functional.
I would expect them to do a little nicer job though, even though the functionality of the parts does not require it.

I bought a few tensioners that were LOUD and this one I'm telling you nice and quiet. Installed with zero effort. High quality.
Don't waste your money on other tensioners like I did this one is great

I run Hayden M6 Tensioners in all my Harleys. Smoother and quieter shifting. Easy to install. Lots of bang for the buck. Great price.
No more primary chain clatter!

Hayden M6

I replaced the stock Harley automatic chain tensioner with the Hayden unit on my 2012 Dyna Switchback. The stock unit only has one direction; tighter and tighter. The Hayden mounts on springs so it keeps constant tension on the primary chain. Install was easy and straight forward. I did have to file the metal portion of the unit a little because the nylon shoe was a little tight in spots on its mounting bracket. After filing, the shoe rides up and down smoothly in the mounting bracket. I also felt the price was a bit high for what you get too. But it is a big improvement over the faulty Harley stock unit. And I felt the Harley Screamin' Eagle unit wasn't a much better design. And its reviews said it was loud. The Hayden unit is quiet.
This thing is awesome

2003 sportster 1200
Good afternoon. My sportster is a stunt bike. Lots of wheelies and burnouts. Is this a good option or will the stress of all the hard riding be bad for it
These tensioners are rather well-made. Certainly better than stock. Yeah, I'd argue it's up for the kind of abuse you're doing!

Will it fit 2019 heritage with a 114

Why 2 springs ?
By Anon.
The smaller spring fits inside the bigger spring. Hayden chose the two-spring design to provide correct, more consistent cam chain tension under all operating conditions.
