Saw a guy in carpark top of Susten Pass with puddle under his bike wishing he had one! (That's a long way from nearest bike shop)
Wish I had one on my Rover 620, drove thru a Cornfield and got a pice of straw through my radiator.!!!! On a bike? Depends on how lucky you feel! Never had one, never needed one, not buying one soon, but how long does your luck last? Do you feel lucky, punk? Well, do you?
