Tru-Tension | Chain Monkey | Motorcycle Precise Chain Tensioning Tool

Easy to setup and use.

They should provide better examples of the chain tension setting. Ducati asks you to measure the gap between the center link of the chain and the swingarm surface. Does this correlate to the measurements provided on the back of the product card? To answer this question, I went to my bike which had the chain tensioned in accordance with the factory service manual, and proceeded to crank down on the Chain Monkey. I found that it came close, I had to really crank down on the Chain Monkey to match the setting. So I feel the Chain Monkey may get me there, but more consistently each time. The crank knob kept coming apart, the end cap kept popping out. Overall: 5/5 stars

Works pretty much as advertised. Adjusting a motorcycle's chain slack can be a pain. I basically have to lay on the ground to see what I'm doing. All motorcycles are different. Most people don't have a lift. The first time takes a little trial and error until you get this tool dialed in. Once you do, just leave it set. If you have more than one bike mark it with a paint stick in two spots. Next time I clean and oil the chain I'll stick this thing on the chain and crank it down to the rubber washer and if their's too much slack just loosen the axle nut and remove all the slack. Another tool for this job is Motion Pro's Chain Alignment Tool. If you have an older bike with miles on her clock things tend to get a little more loosey goosey. I'm throwing this tool in my AWOL Bag. Nuf said.

easy to use, works excellent, reconended

I really wanted the Chain Monkey to work. The concept seems sound, however the implementation is not. On my chain and on the first try, the tool's domed nut was getting ground down by the chain, and I found metal shavings from the nut on the chain. I could feel the nut grinding away, so I backed it off before I even achieved minimum tension. Upon removal, I found a deep circular scar on the nut. Would this mean it would require regular recalibration to account for the lost material? Possibly. In any case, I'm not thrilled about the idea of leaving metal shavings on my chain and wearing down the tool with every use. It really needs a redesign to allow the nut to swivel on the screw so that the nut isn't rotating against the chain.

Definitely need to watch some YouTube videos to know what your doing and play with it but once you get the hang of it. Pretty simple

I wrote a review for the LED product and how it didn't fit. However, this works. Just follow the instructions for proper chain tension. I used this product to calibrate the other chain tension product (BP Racing I think).

This is a brilliant product. It should have been created decades ago. No question about consistent chain tension. Just find the correct adjustment, and mark it. When it comes time to adjust your chain, put this little guy on, and adjust. Done in 30 seconds. No measuring.
