Collection: Spark Plugs
What can we say about spark plugs - all motorcycles need them and they should be changed regularly as the electrode will wear out over time. Performance spark plugs produce a larger spark for more power at high RPMs. This improves throttle response and fuel economy, with less spark plug fouling (reduced voltage to the firing tip causing the cylinder not to fire properly).
