Yamaha Electrical Parts

Spark plugs, plug caps, coils, kill switches, start buttons and wiring for Yamaha YZ250F, YZ450F, WR250F, WR450F and the YZ two strokes.

Spark plugs, caps, coils, kill switches and start buttons for the Yamaha range, sold by model and year. The four strokes have run electric start since 2018 on the YZ450F and 2019 on the YZ250F, so starter parts are listed for those years on.

A spare plug and a kill switch in the toolbox save a weekend. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.

    Questions riders ask

    Spark plugs, caps, coils, kill switches and start buttons for the Yamaha range, sold by model and year. The four strokes have run electric start since 2018 on the YZ450F and 2019 on the YZ250F, so starter parts are listed for those years on. The plug listing names the models it fits; message us with your model and year if it is not clear.

    Two strokes every 10 to 20 hours, or sooner if it fouls. Four strokes every 40 to 60 hours. Carry a spare and the tool to change it.

    Most universal kill switches and start buttons fit any 22mm bar; the plug on the wiring may need changing to match the loom. Model specific ones plug straight in.

    Not sure what fits? Set your bike at the top of the store and every list narrows to parts with confirmed fitment, or message us with your model and year.
