Reproduction main wiring harness for the Honda CB550K from 1977-1978. Tired of tracking down electrical gremlins due to old broken wires or corroded connections? Or maybe you're rebuilding a 550 and it's the perfect time to replace that 35 year old wiring harness! Wires get stiff over time if they're exposed to typical varying weather conditions, they can crack, split, rust and create annoying situations or even dangerous ones.

Check behind the headlight and under the left side cover. That should quickly reveal the external condition of the wiring harness, feel the plastic connectors to see if they are brittle and flex the wires to see how stiff they are. Rather than replacing sections of the wiring harness, for piece of mind and to save from future ?? "is this the result of poor connections?" replace the whole thing. Ride your 550 anywhere with confidence!

We also carry the sub-wire harness separately here.

    Good Quality Product

    I fitted this to my UK model CB550F2. Some of the wires had different colours than the original so needed to trace each and compare to the old harness but I got there in the end. I guess it can't be all things to all people. Very good quality connectors and it fitted straight in otherwise. I bought the sub harness as well and was glad I did.

    Matches up perfectly

    I'm an absolute novice and was able to install this (though I'm still trying to figure out turn signals and brake light), but everything matches up perfectly. It would be helpful if they noted on the harness which end is the front/ rear, but I figured it out eventually.

    Great quality and laid out perfectly. It saved me a lot of time. Great investment on a 50 year old bike.
