You'd at least need a new rear wheel. The hub is a different set up for the disc vs. drum.

You should try to use one of those sprakes? sprocket and brake in one. I think those look slick.



I have no information on these i just think they look cool, good luck with the swap.

If you like your wheel you can get a more modern hub and lace it in. It's not a bad job but it takes some fitting. If your bike has the crossover brake pedal you'll need to fab something to be able to actuate a master cylinder.

Also, you'll most likely need a custom rear axle as most disc hubs use atleast a 3/4" & I'm pretty sure yours is smaller and metric. Yeah, metric, lol.

I recently went the opposite direction with my ironhead and I think going from disc to drum was an easier venture...but it isn't that bad. Just be patient.

Mine is a 76 with the crossover. I used the crossover tube left over from removing the brake to move my shifter to the left side then retro-fitted evo forward controls to the stock front motor mounts and bolted a master cylinder to the cam cover...but then decided I liked the mechanical drum better but I left the brake pedal on the right side.
