the advantage of a manual CCT is that you don't have to rely on spring-loaded tension to determine the position of the tensioner rod
they can't "fail" unless that rod actually breaks off (which it won't). unlike the auto ones.
you should get one from Krieger because he's actually a real person who machines them himself
he and i have emailed many times about upgrades to the klx 250 and I would definitely choose to support him!
