I'm trying to figure out if I can get the URL for an RSS feed for just one specific model of motorcycle, the Yamaha XS650. If I type XS650 into the search box, it shows me the results and includes the RSS button at the bottom. When I filter that search to just show motorcycle listings, the RSS button is gone.

Here is the RSS feed I get when I use XS650 as the search keyword:

I got that from the bottom of this page:

What I need are the results when you click 'Motorcycles' under categories in the link above.
That looks something like this:

Basically how can I get the equivalent RSS feed URL for the results in the link above? Is this possible?
