Automatic KTM Timing Chain Tensioner for RC4, RF4, and XC4 engines.

SKU: TCT-KTM Category: Tags: , ,


The Dirt Tricks KTM Timing Chain Tensioner resolves issues with a slack timing chain on the new 4-stroke motors. The 2008 and newer four-stroke KTMs (and some earlier SX models) use a timing chain tensioning device intended to develop its force using the engine oil pressure hydraulically. The OEM components have serious flaws, which can leave the timing chain in a slack condition. This can have disastrous consequences. The Founder of Dirt Tricks developed the KTM Timing Chain Tensioner as a simple, effective, and fail-safe replacement for the OEM tensioner. It correctly captures the oil pressure and uses a positive mechanical ratcheting system to prevent it from collapsing. If you have a “ticking” noise at idle, on your newer 4-stroke, you need this part. Our tensioner will work on all newer 4-strokes in 250, 400, 450, 505, 530 models using the RC4, XC4, or RF4 motor (not for the RFS motors).
