This is a brand new ignition stick coil for the Kawasaki KX 250 F, supplied as a direct replacement to your original unit. On this model the spark plug cap and the ignition coil are built into one sealed component that sits down into the plug well. It is a compact and efficient arrangement, but when the coil deteriorates the cost of a genuine replacement is high. This aftermarket stick coil returns the ignition system to full strength for a fraction of the outlay.
The unit is built to deliver an ultra high output spark for smooth engine operation, with efficient power transfer connections through its two-terminal design. The quality exceeds the OEM equipment and all products are tested before dispatch. Primary resistance is 0.4 ohms and the body measures 121.5 mm long, matching the original Kawasaki dimensions so it seats correctly against the head. Installation is simple, easy and requires no modification to the bike.

Frequently Asked Questions
Will it fit without modification?
Yes. It is a direct replacement to your original unit with the same two-terminal connection and the same seal dimensions, so it drops into the plug well and connects to the existing harness. Check OEM number 21121-0021 on your original coil before ordering.
What comes in the box?
One brand new ignition stick coil, with the spark plug cap and coil combined in a single sealed unit. All products are tested before shipping.
How do I know the original coil has failed?
On a single-cylinder motocross engine a failing stick coil usually shows as no spark at all, an intermittent cut-out, difficulty starting when hot, or a bike that runs and then dies. A resistance check helps confirm it - this replacement measures 0.4 ohms, and a reading far away from that on your original indicates a damaged winding.
Does it suit hard off-road use?
The coil is a sealed unit with a 39.5 mm seal that keeps water and dirt out of the plug well, and it is built to a standard that exceeds the OEM equipment. As with the original, take care not to trap or stretch the lead when refitting the tank and shrouds.
