Federal Motor Vehicle Safety Standards; Motorcycle Brake Systems

요약

We are proposing to amend the Federal motor vehicle safety standard on motorcycle brake systems, in order to add and update requirements and test procedures and to harmonize with a global technical regulation for motorcycle brakes. If adopted, today's proposal would specify an additional dry brake test procedure to test each service brake control individually and with the motorcycle in the fully loaded condition, provide a new test procedure for assessing performance of motorcycle brakes from high speeds, provide a new wet brake test that better simulates in-service conditions, provide an improved test procedure for evaluating heat fade, add test procedures and performance requirements for antilock brake systems, if fitted, and add a power-assisted braking system failure test, if equipped.
