    Tension test tool only
Belt Tension Tester Tool is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from KIND OF A GENERIC TOOL I will be the first to admit that this tool appears to do what it's intended to do. However, I will be the first to stay I have little to no experience at a lot of this when it comes to working on the bike. The most confusing part is reading the marks on the sidearm. Every time I tested it, I would come to the conclusion that the belt is a little loose. I think the belt is ok and that I wasn't reading the marks right.

Rated 5 out of 5 by from Belt Tension Tester Tool I purchased this tool to check the belt tension on my wife's Harley and on my Harley. I make it a habit of checking the belt tension whenever I check the tire pressure because it's easy to test and the "window" on the belt guard to check the belt deflection is right there in plain sight. Nice tool and I carry it in my Tour Pak so it's always with me. Can't ever have too many tools!

Why is there no belt tension measurement for 6 speeds?

The belt tension measurement listed is for 4 and 5 speeds but does not list the measurement for 6 speeds.

Hey sc1282, Thanks for your question. Belt tension specs are different for each model. Specs for your model can be found in both the owners manual and in the service manual for your model. I hope this helps!
