Heavy Duty Chain Roller Tensioner w/Spring 110cc 125cc 140cc Dirt Pit Pro Dirt Bike 4 wheeler White

I liked the install of the chain tensioner - however, I had to go with a different spring. The arm and roller were really what I was after - yet the unit seems to work fine and does maintain spring tension per design. Time will tell how the plastic roller holds up. And the seller sends two rollers so that tells me they may not last long. If the rollers don't last, then the easy fix is installing a sprocket onto the shaft of the tensioner.

Item as described

There is a missing part. You will want to get a 15mm to 12mm bushing in order to fit a 1/2 inch bolt otherwise you are going to find a very hard time looking for a 15mm bolt to install!! Wasted a lot of time searching for a bolt which directly fit this.

Works as it should but the plastic roller doesn’t last very long

The quality of the product was cheap didn't look anything like the pictures shown and when I returned the item I never received my refund.

Installed one on my Baja minibike and it works perfectly! Yes, slight modifications were made to both Frank and the tensioner, but I couldn't have gotten a better fit. I've put quite a few miles on the bike since installing it and wear is negligible. I expect many more miles and I've already ordered another one for the next minibike.My only concern is that removal of the nylon wheel seems impossible because the rod will spin when torque is applied. A minor concern because wear is minor. I do not expect to be changing it anytime soon.

Was not an exact replacement but a little grinder work and a steel spacer and we’re back in business. Fast shipping. Good service

Works great with the side taller.
