That goes against everything I've ever learned during years spent on a motorcycle. As a matter of fact Moto Guzzi employed a hydraulic system that activated a percentage of the rear brake when pressure was applied to the front brake lever, as a safety feature.
I know I use the rear brake more than most. I find it controls my speed better. However if I need to stop or slow quickly, then yes, the front brake is more effective....unless it's wet.
