`82 gpZ750 Front Brake Line Question was created by Unicron0827
Im new here, and new to this bike.
I picked up a really clean gpZ750 a couple months back to setup as a commuter bike to give my touring bagger a break.
My end goal for the build is something a bit street tracker inspired, while leaving most of the original bodywork intact, save swapping the front fender for a brace.

I started to tackle the handlebars last night, and there's just not enough play in the front brake line to fit the dime city tracker bars I planned on putting on here.
Which brings me to my question, does anyone know of a vendor that makes a 20" brace line from the double banjo to the front master cylinder, or the exact dimensions of the line i would need to have custom made?

I'm sure I'm not the first person to go down this road, so this has to have been done before, but as I'm new to this bike and its community, I'm at a loss for where to start.

The '82 GPz750 is a great bike. Congratulations.
You can have brake lines made at hydraulic shops to your exact specs. Or, as Jack recommended, you can go to Z1E/MikesXS and get them in 2" increments with swivel banjos.
I have had a set made by these guys: EL Johnston They can make them while you wait in whatever color/material you want. The cost is similar.
One thing to keep in mind...note the banjo orientation and make sure they are the same as the ones you took off. Don't ask me how I know that...
Good luck,
Jim

@ThatGPzGuy, Figured id check, since it seems you have one of these.
Im looking at Goodridge 10mm Brake Hose 833 series and fittings.
These should be a direct swap in to fit?
The PO put a lot of effort into keeping everything stock, and ideally any changes I make i plan to be in line with that and easily reversible.
so I'm assuming the line on here is stock as well.

Making your own lines from Earl's parts affords you the latitude of getting the length perfect and the hose ends just right for your particular application. The parts are all made in USA and are easy to assemble by yourself.

Glad to hear that. Mine is pretty stock with the exception of the paint and the exhaust. It is a joy to ride but down at the moment doing something similar to you. I opted for Galfer lines but as my projects tend to go, I am rebuilding the entire front brake system.

You MUST get new banjo bolts as well if you buy Goodridge lines. The fitting width is narrower than stock. I love the Goodridge product and have used them multiple times, but new banjo bolts and crush washers are a must.
