Frequently Asked Questions

Will this work with any sprocket size?

This tensioner is designed for use with 34T sprockets. Other sprocket sizes may not be compatible.

Do I need to modify my bike to install this?

No — it mounts directly using your existing OEM hardware with no frame or engine modifications.

What's the benefit of an adjustable tensioner?

Proper tension prevents primary chain slack and reduces wear on the chain, sprockets, and engine bearings. Over-tightening can cause drag and damage.

Is this a drop-in replacement for the stock tensioner?

Yes — it replaces the factory tensioner on compatible Dyna models and installs with factory mounting points.
