To answer, Yes these are the OEM rims. I had a difficult time finding a plating company that specializes in rims. Living in Michigan, I had to pay shipping to the West Coast. The Company owner answers the phone when I called for a quote. We talked for 15 minutes. I couldn't ask for a better guy to deal with.
The rims are easy to care for. Soap and warm water. Never used any polish or chrome cleaner. I use internal weights. Looks like silicone sand. No marks of any kind. Approx. 40,000 miles on them. Total cost including shipping one way, $600.00. I think they improve my bike's appearance. Ease of care a bonus.
