We have a 2011 Harley-Davidson Dyna Street Bob and wanted to give it better braking performance up front, but we didn’t want to spend thousands on this project and break the bank while doing so.
We already had a set of calipers, a newly powdercoated 13-spoke mag, and some brake rotors that were all “take off” parts from a few other project bikes of the past, so we had most of the needed parts just sitting in a box on our shelves.
Using this mismatched componentry we knew it was going to take a bit of planning, measuring, and some basic machining skills to get our pile of parts to work together in unison. Nothing too complicated really needed to be done to make these parts work besides finding the right set of fork lowers. After figuring out what was available with 49mm dual-disc from the factory, we used a set of H-D dual disk lower sliders (part #45500273) from the Harley-Davidson Parts & Accessories catalog that are used on 2014–2016 Dyna Lowrider models. From there we were able to construct a dual-disc setup on the cheap using nothing but new and used OEM Harley-Davidson parts. Here’s how we did it.
