Good used early style cruise control for K75 Series and K100 8v series. These are just the ideal item for those long trips and your hand becomes cramped. Just tighten it up so as to make it easier on the hand but not too tight to be able to back off when needed. This is to just make it more comfortable on the hand. I used it on my last trip over to Perth and back. This may not be legal in all states so check it out first before purchasing.
