APE manual cam
chain tensioners are designed to replace the automatic and hydraulic
tensioners on high performance engines. The automatic adjusters
can back out when the throttle is closed suddenly at high rpm.
This allows the cams to go momentarely out of time, and can result
in bent valves and/or serious engine damage. Hydraulic tensioners
have a tendency to put too much tension on the chain guide under
high rpm/high oil pressure conditions, resulting in premature

No mater what the engine does, the cam chain tension will remain
constant. An APE manual cam chain tensioner is a must for any
kind of performance riding.
APE manual tensioners
are CNC machined from billet alloy to exact tolerances for perfect
