EK Cam Timing Chain For Honda CRF100F XL100S XR100R CRF100 XL100 XR100 – K&L Supply

If you're rebuilding the top end on your Honda CRF100F or XR100R, don't reuse the old timing chain—grab this fresh EK unit from K&L Supply.

This is the real deal, part number 12-0445 EK25H90L, and it’s made to handle the job.

Fits a bunch of the 100cc bikes like the XL100S and CRF100, so whether you're restoring a classic or fixing up a pit bike, this chain is what you need.

It’s brand new in the package, never installed.

Just make sure you line up those timing marks right when you put it in.

Solid quality, no funny business.
