There are similarities in handling between my motorcycle and my bicycle; the biggest difference is you have some serious braking capability on a motorcycle. Bicycles don't have brakes. They have speed modulators. I doubt bicycle disc brakes would improve things all that much. Bicycles are more limited by the lack of traction available from skinny road bicycle tires.
The biggest difference is a motorcycle has suspension. The majority of handling on a motorcycle is the suspension and it's set up, secondly the rider and then brakes if you even want to count them for handling, but I have always found brakes on a motorcycle good for stopping at the end of a descent or slowing after out of a corner.
