I would suggest that along with staying on top of what gets posted in this forum, that you also always check ebay and amazon for any new products that pop up as some vendors are quick to throw their products up their.
Good point, it might be worth it to speak with a few dealers to see what they have, hopefully they have the catalog.The 2015 Harley Davidson accessory catalog has lots of stuff for the Street. Quite a bit more than on the HD website. Perhaps the dealers in India have the catalog. Then your sister could order and bring so stuff to you. I would think that any Harley shop in the US would help her out.
