These are fitted to the FTR Carbon and were removed from the aftermarket availability list in the UK a few months ago, my dealership were after a set. I suspect Indian may be heading in a similar direction as Harley-Davidson CVO models where to maintain exclusivity on limited edition models you will need a VIN number to order them?
You could get the originals reworked to turn them black and there are a couple of ways of doing this but that too can be an expensive process. Look up ceramic coating process.
