CB550 Custom Build by S&G builder Brady Young


May 2013 Black and Tan
Custom build by Seaweed and Gravel in southern california built by Brady Young. The inspiration for this build was spawned from a previous personal bike of Brady's, made from spare parts and a few weekends. The bike was rough, full of character, and frequently saw the dirt. Nonetheless, it caught the eye of the client that commissioned this build, but with new shoes and a classy attire. 

Our goal for this build was to create a simple, clean, minimalistic bike with an aggressive, low stance; pulling elements from both the cafe racer and brat style palettes, whilst preserving the classic lines that were buried in stock form. Once the form and stance of the bike was set, we moved forward with making it function.

The top end was rebuilt with new internals and tuned by a retired racer and mechanic of the time, making it a true one kick cold started. The client wanted a kick and electric start, so we called upon the guys at Antigravity Batteries. Their compact, powerful battery powers the new from scratch harness with an updated rec/reg combo. With this setup we were able to retain our goal of a clean and minimal design.

Our theory on the finish of our bikes is overall modesty with bold features.  With an all black bike we incorporated matte, satin, and gloss finishes to add some contrast. We here at Seaweed And Gravel feel we've produced a bike that we can be proud of, and have welcomed a new member into our family of weirdos. --Brady

    this bike is exactly what I have been thinking about buying! As soon as a saw it I was astonished at how perfectly my vision of a fantastic cafe style bike could be transcended through another person or vice versa lol out of curiosity how much did the bike cost after the build and do you ship to illinois? Btw you all are very skilled at what you do and I take my hat off to you all
    Sincerely

    Hi I’m planning to built a similar bike like this im not sure about the specs so wondering did you guys use the same fuel tank or if it’s a new one what size or model is it and what is the size of the headlight…. What type/style of Handel Bars are they ??? And what type of blinkers did you use for the front and back …. This is my first project …. I don’t know a lot about them so I researched a bit and I liked this model a lot it would be really great if I could get these information so that I could use it for my bike cheers …. Thank you

    If you don’t mind me asking, what antigravity battery did you use on this bike? The 4 cell or 8 cell? Also, where did you hide it?
