Automatic KTM Timing Chain Tensioner
- If you have a "ticking" noise at idle, on your newer four-stroke, you need this part. Resolves issues with a slack timing chain on the new four-stroke motors.
- Uses oil pressure combined with a mechanical ratchet system to prevent collapse.
With very satisfying test results from our race bikes, we have completed CNC production of the new tensioner. They can be installed in less than five minutes.
As the spring is inserted and you compress it, you can feel and hear the clicks as the piston ratchets into position. There are a total of 11 ratchet positions at 1mm spacing. If you extend to more than 9 clicks, you probably need to replace your timing chain.
Below is an overview of the OEM design verses the Dirt Tricks design.
