They have fitment problems on R6s. Shouldn't be in issue with the piece in question, since it only uses two screws to bolt up to your cluster/ headlight brackets (forgot which). The quality of the screen itself is very good.
$12.50 might be a lot for shipping, but the total is still twenty bucks cheaper than motowheels' own retail price (shipped). High shipping on eBay items is pretty standard practice because it means more money goes to the seller, instead of to eBay.
