Re: Pushing the handlebars?
He's talking about conter steering. Say you are entering a right hand turn at 30 mph - to initiate a lean in the bike you can briefly, gently press on the right control. Yep pointing the wheel to the left a touch. But that causes the bike to lean in response. More press = more lean.
One can just shift weight as well, for gentle curves. But a touch on the controls will bring the bike over more quickly.
