This manual cam chain adjuster allows you to adjust the pressure on your cam chain manually.
This system goes back to the early Honda years where all bikes had such a manual cam chain system installed.

The absolute benefit from this system is that you have total control on the cam chain tensioner pressure.
The downside of this system is that it's more maintenance sensitive, which means that you need to check the cam chain pressure on a regular basis.

This is a perfect system for racing applications.   Fits all 2013-Current Honda CRF110’s.
