Reply to Bill's Post: Ok, I appreciate the answer, however i would like to know maybe if there is any way that you can let me know How i would change it, as far as how would i modify it. The process it would take to modify it. If at all possible. If you don't know, thats cool. I appreciate the help anyway. But if you know any tricks that could help. The motor is a 72 XLCH, the frame is a 73 Sportster, and has a swingarm. If that helps give anymore of an idea. This is my first bike ever, and I'm rebuilding the motor, and starting from the ground up. Thank you for your time.

Hi Mac,

Unfortunately that will be quite the undertaking as the most important part in making a rear disc brake work is the anchor to the swingarm that is necessary. Other issues that you are going to encounter are like Bill mentioned, the fact that it is a sporocket drive/brake hub assembly, you would need a newer disc equipped wheel that is probably a pulley drive set up, therfore creating the need for a front pulley coversion or a rear wheel sprocket conversion.

Wheel diameter, width & axle size are your issues to overcome when searching for a wheel to fit, then you need to work in the sprocket conversion as well as mounting the caliper and the anchor. It's doable but it will require quite a bit of time & enginuity to get it mounted properly. I haven't done one of these as I mostly light Ironheads on fire, so
I can't say do, this & this & this, and ultimately it depends on your donor wheel & the brake caliper you are going to use.

I can point you in the right direction, if you have more questions let me know.
