HIAORS Heavy Duty Chain Roller Tensioner w/Spring for 110cc, 125cc, 140cc Dirt Pit Mini 🚲 Bikes, Moto ATV XR CRF50, 110, 125 SSR SDG, Pit Pro Dirt Bikes, 4 wheelers - Black Review

Well it would be a better product if it wasn't plastic but otherwise it's a good product. I think the fast shipping of course arrived the next day which was amazing!

Actually bought for parts. I need the spring from my other chain tensioner. This one seemed to look stronger than my original. I would wear it but it didn't fit. Also, I recommend for any project you do.

Easy assembly, after about 5 minutes of driving on bumpy roads, the chain tensioner pops out of the spring. When you close it it works great and stays in place (see attached photos). Unfortunately the regular one is very worn out so I replaced it with this one. So far, after about 4 hours of driving and screed, it's holding up. Mounted on Coolest MountOPZ 125cc youth ATV. See 2017.

Excellent product! That works great! I installed it on my db30 doodlebug mini bike so I can be constantly stressed while riding. Mini bikes are notorious for stretching and throwing chains. I haven't changed the chain since I installed these. You can tell when the chain is stretching and loosening too much as the tensioner starts to operate much more frequently. At this point, simply install the new chain and you will have no problems on the track! My only recommendation for improving the next…
