Research sources

When trying to find real information about a bike manufactures sources are usually worthless. You get the basic tech specs but everything else has to be dug up from forums adn the like. Magazine articles are sometimes useful but the the test they do are no where near as usefull as real owner reports.

Advrider.com

Advrider is a gold mine of information on anything adventure riding related. I find it also to be more balanced that your usual Brand X fan forums. It's usually more about riding than any particular bike and that tends to bring out the more honest down to earth opinions.
