Far as I know it's a 73 Triumph front end, Lockheed disc, with a 70? Honda
master cylinder. Works well, but I need a shorter top line to make it pretty with the low bars.
That's the way I got it, and one of the main selling points for me when I first saw the ad. I had that front end/brake on my 74 Trident, and I love it.
I have pictures from the other side, but the light is better from this side.
