Personally, I would stick with OEM Honda, Gates, or Goodyear Gatorbacks. The Gates and Goodyear are American made. At this time, some Honda OEM parts are being made in China, and I don't trust Chinese parts to last or work.
At this point in time, their quality and standards are near 1948 Japanese era. There is one well-known online Wing parts supplier, with a bad reputation, that shows Japan made belts in their ad, but what you get are Chinese made.
The difficult can be done in a day. The impossible takes a little longer, if you don't know it can't be done.
