Sportster Rear Caliper Conversion
Caliper Strut Mount
Here we are to date. So you can start to see the theme of the bike starting to emerge. I am calling this design The "Streat Beast"!. Updating where I can and have a reliable street, in town, not a crusier bike. Over all Hugger Orange with a black racing stripe.
So far the rear disk brake conversion has gone well. The old sportster came with a 130 rear tire and the 2002 came with a 150. I have played with the idea of putting a 140 on it. However with this mockup I just used the 130 original and I think I like it. Sometimes you have to ask yourself why? I did that and came up with no logical answer. So I think I may just stay with the 130/90/16. I like the look. I did also stay with the original 1975 sportster rear fork.
The shocks were picked up off of Craigslist and I plan to mount the caliper at the same angle as the shocks. Will be stabilizing the caliper with a rod and heim joint to the rear fork.
I like it! Clean with good lines, simple and should stop great.
To keep the caliper stationary so it doesn't rotate I have chosen to mount a strut to the swing arm. I used a metal gate mounting bracket and mig welded a bolt guide through it. I then welded it to the frame and I was done except for the strut itself. The strut has heim joints on both ends. Used a carbide ball end to round out the weld and then finished with a sanding roll.
