The old school guys will tell you to just cram three fingers under the chain to set the slack and send it.

Ok sweet. And if you happen to have 58mm fingers (less the thickness of the chain sliders) then you're chain's in spec. 

But if not who know's what the hell slack you'll end up with.

Excessive chain wear, sprocket wear, slider wear, left side wheel bearing failure, primary shaft bearing failure, primary shaft oil leaks can all be the result of improper slack adjustment.

You can set YOUR slack with a finger, a toe, a block of wood or just wing it, but we'll be setting OURS with the Taco Tensioner. 

• 3D printed to the exact factory tension
• Innovative locating cam on the bottom to ensure exact placement on the slider 
• Delicious taco shape to confirm it's working
• Lifetime guarantee 
• Pack with you on the trail, weighs virtually nothing 
• Compatible with Polisport swim arm guards installed
• NOT compatible with TM Design Works Baja Edition 1, 2 & SX chain sliders  

*The upper plastic pant leg chain protector on the street legal dual sport bikes must be removed to make clearance for the adjustment tool.

FITMENT: 

Any late model KTM 125-501 dirt bike with 55mm to 58mm of chain slack measured from the top of the swingarm.

If your manual describes this same adjustment method this tool is compatible with your bike.

HOW TO USE VIDEO

 
USE:

1. Unweight the swing arm.
2. Slip the Taco Tensioner under the chain and place the locating tab on the bottom of the tool into the hole on the back of the chain slider and push the tool forward until it stops.
3. Grab one link of the chain and twist it back and forth. There should be a very slight play to the link. Adjust the chain slack as needed to find this point of tension in your chain.
4. Remove the tool and Send It🤘🏽.
