Just found these cleaning out the garage yesterday. Stock levers from my RSV4. In great shape, had less than 3k miles on them with no marks/abrasions/etc...

edit: these came off a 2010 RSV4-R. I haven't checked part numbers to see if they will fit on other years/models

Also have the DB killer from a Leo Vince GP Evo II slip on for the RSV4.
$50 shipped for the levers (cheapest way I can find, probably through USPS)

Whatever offer you come up with for the DB killer.
