The manual cam chain tensioner is designed to provide greater precision and
control when adjusting cam chain tension, representing an alternative to
standard automatic or hydraulic systems.
Thanks to the manual adjustment, it allows the desired tension to be set
accurately and maintained consistently over time, reducing the variations
typical of automatic mechanisms.

This feature makes it particularly suitable for sport use, intensive
applications, or for riders who want direct control of the valve timing
system.
Correct tension adjustment contributes to smoother operation of the timing
system and can help reduce noise and wear of the related components, such as
chain guides and sprockets.

The tensioner is fully CNC-machined from billet, with anodized aluminum body
and steel adjustment screw.
