The simplest to use ‘pass / fail’ chain tensioner gauge ever designed.

If you’ve ever been perplexed by the chain adjustment method on your KTM or Husky this is the smartest and simplest way to adjust your chain there is.   

Stop using the inaccurate and inconsistent ‘3-finger’ method to adjust your chain. It’s trail side folklore that costs you money and hurts your bike.

Imagine adjusting valves, spark plug gap or anything else important and expensive by ‘winging it’, so why are we still doing that with something as essential as chain slack?

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.

• 3D printed to the exact factory spec tension
