If you have a question about some general motorcycle topic such as, what kind of luck are you having with Brand A riding widgets, don't post it in the Kawasaki forum just because you are using your go fast widget on your new ZX6RR. If the topic is general and doesn't actually pertain to the specific bike then post it in this General Area or another appropriate one.
A question on what type of Bridgestone tire works best for mountain touring doesn't necessarily need to be in the Suzuki Forum because you are touring on a Katana 750.
The info may be useful for others that may never really check the specific forums since they don't ride that brand of bike. I think most check them all but some don't.
