All the ones I'm seeing on there are aftermarket (not OEM). They seem to be $500-$600 when you include shipping. With those ones (aftermarket from China) quality can be spotty so it's really important to be able to discern which ones are well-made and which are not.
Three of the folks I ride with both sets for their CBR 600 RR's and they were really happy and the bikes looked sharp. Quality on those specific units was very good
But at that price, I wonder if OEM might be less money? Over here they are not that bad but I can't get anything for the older models as they were not sold here (grey market bikes).
