I've used the larger version for dusting my pickup truck and it lasted for years and years, so I decided to buy this smaller one for use on my motorcycle.  But.............I would suggest you don't use it immediately on your motorcycle as they use some kind of wax, or waxy ingredient to treat these dusters and if you use it straight out of its plastic bag it will leave streak marks on your paint.  I will use a new one first to dust items in my shop or the house, get it slightly dirty and dusty.  This keeps the duster from streaking on your bike.  I think the dirtier these things get the better job they do.  I usually just take mine outside after each use and shake the crap out of it then stick it back into its plastic bag.  I think it works great for that quick dust off prior to hitting the road and in between washes.
