Most the factory stock filters are pleated paper element type.
They are very effective.
I would be surprised if you needed to remove yours and blow through from the backside with compressed air more than once or twice each year.
I don't care for the K & N's... they are too pricey, require more maintenance, and I'm Not a racer.
Did I forget louder, smellier, and messy ?
Almost any mc/scooter mechanic can give you one of the K & N stickers if you ask.
Nearly as good as running one.
