I just go to the Honda dealership & get the chain and sprockets. I think they had to order them from partsnmore or somewhere...
I don't know about your dealership, but when you order through them, you don't have to pay shipping.
For instance, if I ordered the chain and sprockets through an online company, I would have to pay shipping, but if I order it through the dealership, I don't have to pay shipping.
I get the standard sprockets that heffay mentioned.... I've never got the renthal sprockets.
