I just googled the same thing. Quite frankly I don't blame OP for getting it wrong, because the top result is from Cornell University.

If you're not already read into bicycle or motorcycle dynamics, the top google result sounds reasonable. Which makes it all the more ironic because they're talking about research which demonstrates, among other things, that it's a misconception to believe that gyroscopic forces are necessary.
