The only way to check is through magazines that actually weigh a bike and specify how much gas was in it when they did. In an interesting anonymous letter to the editor from someone in the industry (years ago), the author said that the reason Japanese manufacturers' claimed dry weights were so low was that they based them on the specs for the parts. That is, using design specs they added up the weights of each individual part. And they did so because they needed to publish the specs long before any bike of that model year was produced.
