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 (reviewed below), which can leave the timing chain in a slack condition. This can have disastrous consequences. Dirt Tricks has developed a simple, effective and failsafe replacement. The new tensioner correctly captures the oil pressure. Additionally, it uses a positive mechanical ratcheting system which prevents it from collapsing. The replacement unit will work on all newer four-strokes in 250, 400, 450, 505, 530 models using the RC4, XC4, or RF4 motor (not for the RFS motors). This means the following bikes:
With very satisfying test results from our race

installed in less than five minutes. The price is $89.00 Please call if you

Installing spring. |
| 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 10 ratchet positions at 1mm spacing. If you extend to more than 9 clicks, you probably need to replace your timing chain. |
