Making the argument that a 600+ pound air-cooled iron v-twin with belt drive and a flexi-suspension is a "performance vehicle" that needs state-of-the-art brakes is absurd. Different bikes, different missions.
Any, and every, vehicle can benefit from having better brakes. To make an argument that just because a Dyna won't lap the track the same as a CBR (or any other SuperSport bike) then it doesn't need the best brakes possible is flat idiotic. That would be like saying "I don't care if these tires actually stick to the road, as long as I don't have to buy another set in 5 years. I mean, it's not like I want to take it to any track days."

The reality is that tires, brakes, and suspension are three main components of any motorcycle that contribute to the rider's safety. It should be every rider's goal to have the best of those components as they can afford. The benefits of upgrading those components will not only add to the safety provided, but also improve ride quality and comfort. It's not only about being able to knife though a set of corners at light speed, but the ability to make emergency maneuvers at any given time.

I agree. Besides, overkill is underrated.

The only people that say you shouldn't improve your brakes are people who have never ridden a bike with great brakes.

I have no idea why I would ever wade into a conversation on anything but adding more cubic inches on an H-D site...

It's funny, there's always all this big talk about adding cubes to a motor when the first thing I think of is if it goes faster you need to make it stop better. But not here because they aren't racing bikes?

Now are you really trying to add all those cubes just so you can run with an "average" 1,000 cc anything else and not the "high performance" version of anything else? Which is what you'll end up doing. I cannot begin to follow some of the logic...

Sorry, I'm a motorcyclist and I ride everything and H-D brakes suck, they're famous for it. Even a well stopping bike like the Switchback brakes, which can out stop some sport bikes, suck not because it doesn't stop well but because there is no feel. Put another disc and I bet I'll get more feel because I'm not clamping down on a single disc to get the same effect of a braking load spread over 2 discs. But maybe conventional braking wisdom doesn't work on Harleys because it doesn't add more cubes.

Sorry guys, just had to joke about that a bit

I thought that I'd actually participate in this Harley forum because so many Dyna riders seem to be former sport bike, adventure bike, and whatever other rides compared to the Softail crowd...

The confusion here seems to center around the assumption that different brakes, or more brakes, or brakes modeled after race bikes, will be "better" brakes.
I guess the most convenient thing to do is stick with ones pre-existing beliefs, and ignore actual test results, such as the single-disk Harley Rocker having a shorter stopping distance than all the "superbikes" in the set of data in post #23. And a stock Harley Switchback (considered to be a "cruiser") having a shorter stopping distance than most of the sportbikes in this other test:

Whether the "feel" meets with your personal approval or not, it apparently didn't prevent the test riders from getting highly impressive results. So maybe the most useful and practical approach would be to recalibrate your sense of feel to what is actually proven to work well, versus letting your pre-existing beliefs and prejudices dictate what the feel should be.

Exactly. They do not know what they are missing. I love good brakes.

i have said nearly the exact same thing over and over. the forum is more hp, more tq, ... brakes? for what? ... "adequate"

adequate? seriously?
adˇeˇquate
ˈadəkwət/
  • adjective
  1. as much or as good as necessary for some requirement or purpose; fully sufficient, suitable, or fit (often followed by to or for): This car is adequate to our needs. adequate food for fifty people.
  2. barely sufficient or suitable: Being adequate is not good enough.
  3. Law. reasonably sufficient for starting legal action: adequate grounds.

    http://www.dictionary.com/browse/adequate

would you accept an adequate life?

I don't accept adequate. Skimping on brakes and tires is not something I would do.

Simple Really...

First for clarification...the "Install Instructions" reference "04-later" Dyna (which really means 04-05 only, btw instructions latest "Rev" in 2004) because in 2004 they changed to a 1" axle (except FXDWG) requiring new sliders. The MoCo made these kits also for 3/4" axled Dyna/Sporster.




From 2000-2005 All Dynas came equipped with a wheel (Laced Spoke or "Mag") that would except a Right-side Rotor thus a simple all inclusive Dual Disc "Kit" could be used to convert without any fanfare.

In 2006 with introduction of 49mm tubes, the sliders were redesigned with no Right-side brake provisions available on any model along with the "mag" wheel dropping the Right-side rotor mounting. Only the redesigned Laced Spoke was still able to mount a right-side rotor, but without a proper right-side slider...who cares.

No Parts available for kit = No Kit "Discontinued"




Along comes the Fat Bob, finally dual discs again...wait, oh...it has different fender mounts, but people "muddle" through that because of the starvation from not having dual discs. A lot of people just "couldn't do it"...their OCD wouldn't allow having different right and left sliders. So they got a matching pair of Fat Bob sliders...wait, oh...That Fat Bob slider is a wide-glide slider with caliper mounting moved more inboard than the mid-glide, so then people were milling their calipers to get them moved back out.

The Moco would never endorse putting a Right-side Fat Bob on a midglide and the "mags" still would not except a right-side rotor. Thus NO "Kit"




Fast forward to 2014, the NEW FXDL Low Rider is released with Dual discs and LR only wheels. Everybody, well a lot people anyway, loves it.

No kit now?...Can't be just one simple kit anymore..."with or without ABS?" etc., coupled with most likely needing an appropriate wheel (unless you had and wanted to use a Laced spoke wheel) and the individual required parts for your particular application are available through the Parts Dept = NO "Kit"
