New “A” front brake hose for 74-75 CB550K & 69-75 CB750. This is the hose that runs from the front 3-way splitter to the front brake hard line. Here’s a tip: rubber brake hoses are known to break down from the inside out, therefore it’s not always easy to tell if a hose needs replacing. If it’s old, throw it out and replace it! Replaces OEM#45125-300-003. Made in Japan. Check fitment info for all models and year ranges this part fits.
