OOOO more motofom ideas. Put it in the pedals. That'll stop any stones getting caught. Because that happens loads

IIRC the moto foam in pedals is to stop mud filling them up, working by the theory that foam weighs less than mud.
But it backfires, as the mud just sits on the pedal, instead of getting pushed through the holes which have been filled.
And yes, the Sam Hill joke is just old now.
