ABSTRACT:
An anti dive device for a motorcycle having a front wheel supported by front forks, each fork having an inner pipe and an outer case. The outer case of each front fork has two chambers filled with working fluid, at least two working fluid passages of different sizes between the two chambers, and elements to select which passage is open between the chambers. The device further has two brake assemblies and a hydraulic pressure generator. When braking torque is applied to the first brake assembly, a caliper bracket connected to the first brake assembly activates the hydraulic pressure generator, causing the activation of the second brake assembly as well as the selection of the smaller working fluid passage. Restricting the size of the passage causes the fork suspension to stiffen, thus preventing the motorcycle from nosediving upon braking.
