Lower brake hose kit for many of the early disc brake 450/500/550/750 models, please read the fitment list below.

If your brake lines are original they should probably be replaced..... It's one of those things you've been meaning to do, now's your chance!

We have banjo bolts available separately so you can choose your color!

Kit Contains:

Reproduction Lower Brake Hose - 14.5" - (threading 10mm x 1.25mm) Connects between the 3 way joint under the headlight and the metal hose that attaches to the front brake caliper.
Genuine Honda Brake Pipe - Hard-line that connects between the lower brake hose and the front brake caliper.

Replaces Honda Part Numbers: 45125-300-003, 45125-379-003 (lower), 45128-323-020 (brake pipe)

Note: This kit fits this type caliper which was used on most of the models below. It does not fit the early finned style caliper used on the '70-'71 CB450K and early CB750K's. The lower hose in this kit is 1.5" longer than the original hose on some model years.
