I have them on my bike. The braided don't expand in diameter when under pressure like the weaker stock ones. You won't have any spongy or mushy feeling under hard braking. They feel solid and have more braking pressure/power. You should notice it on the street more than dirt. I always did on the bikes I put them on. Not a huge difference, but enough that some of you will notice.

 

I just got my set:

Look extremely well made, looks like it is designed to remove the existing steel line/hose combo & replace with the 1 pcs SS



Thats exactly what I am looking for.

 

yay! still waiting for mine...

Order processed, but not shipped yet...

 

OK, I got mine.
The rear was an exact match.
The front was not. Mine came with a 90º bend at the master cylinder. I mounted it fine, but I'm curious if it is the wrong line. It's way too long, even for a 300, the loop goes way up and over the instrument panel...works great though.
I'm going to call and see if I can replace it for a nominal fee.

 

i received mine too but havent tried to mount it. Can you take a pic?
My front has 1 90deg bend for what I assume is for the brake caliper. It is 63" long including the bend.

 

Any close up pictures of the mounting?

 

I'll get some pics tomorrow, as well as a measurement. But it's just like drm's.
I mounted it with the 90 pointing upwards, after an initial level mount and gravity bleed with the bottom of the hose disconnected. Once bled through, I pointed the 90 upwards and back towards me. It looks totally stupid. I mounted it with the lower clamp loose and the hose not routed through the fork guard tab, once I routed it properly I realized the length issue.
My real question is does the KLX 300 really use this line? Does it mount in a different spot on the master cylinder than the 2009+ 250? Seems unlikely, but certainly possible...
As seen with others trying to swap brake parts between models.
I made it work, it will last until I get a replacement or it gets caught on something.
You'll see what I mean when I get a picture...

 

I figured the bend mouted at the wheel and not at the handle bars. Looking forward to your pic.

 

I thought that too, but the casing is on the bottom of the hose and it even has a nice extra rubber piece to fit in the fork guard clamp.
They work great, even if not completely correct.
Curious to see what they say.
I need to find a part diagram that I can take a screen shot of to compare 250 and 300 parts.
Found it. It's the wrong fitting for sure.
Screenshot is from Bikebandit's listing for OEM brake parts for a 2007 KLX 300. Notice the straight fitting?
