You're not doubling your braking power - you're still limited by the contact patch of the tire up front as well as other factors such as pad swept area, pad composition, suspension compliance, etc. You're also adding unsprung weight which affects other aspects of the bike's handling.


The biggest benefit you'll get is better head dissipation and possibly reduced lever pressure. There are a gazillion threads on here debating the pros/cons of dual rotors on HDs...and no definitive answers. YOU will know whether it's worth it for you. I think you can get huge improvements on the stock system by changing out the pads, lines, and maybe calipers. But the truth is that the standard Dyna single rotor is adequate for the majority of riders out there. I'd recommend trying to upgrade your existing brakes first, and if you're not satisfied with that, doing a conversion to duals. I think trading off the bike just to get another front disk is overkill...but that's just me...

Of course two discs are better than one. I suppose it depends on your riding style as to whether it makes a difference.

I find I ride my Honda very differently to my Harley due to the fact it brakes so much better, and I have a fat Bob with two discs upfront.

I don't think 2 is automatically better than 1, but all else being equal, I don't think they'd add the second disc if they couldn't make use of it. I don't think there is a disadvantage of having too much braking assuming you have ABS.

I haven't ridden a Harley with ABS. My 2008 doesn't have it. I do know that my 2000 BMW R1100RT that has dual discs will stop much faster than my Harley. It's actually not even close, but I think its a function of completely different technology more than number of discs.

There was a test a year or so ago in Motorcyclist or Cycleworld where the Wideglide stopped from 30-0 and 60-0 in the same distance as a Honda CBR600RR....They couldn't believe it! Yes the HD had ABS

Your brakes are fine.

Has anyone put a buell front end on a street bob? I have seen it done on a FXDX. I always thought their front brake was badass.

yeah... mine doesn't... no abs. 15" rotor, lyndall z+ pads, s/s line. stops like a train. currently working on a dual disk conversion

same issue with my sporty prior to converting to dual disc. now stops on a dime.

there's opinions, then there's the truth. ... whole lotta opinion in this thread... xl1200r, xr1200r, xr1200x, 1200 sport, fxdx, fat bob, low rider, and low rider s have dual disk set ups just for show... they don't actually slow the bike down....................

I can't compare dual to single, but I have the same bike in ABS also and I can help u compare it to the best of the best.

I've ridden race bikes all my life that stop on a dime. I can tell you, the single disc ABS is very adequate. I've done emergency stops on the race bike many times and comparing it to this HOG, although the race bike is much better of course, I can tell you that I'm not disappointed at all with the single disc with ABS on our bikes.

You don't need to worry. Will dual be possibly better? sure everything helps of course. But I've done some emergency stops on this HOG with abs, and I can tell you that I have confidence in my bike right now and that's comparing a sport bike which is a bigger difference than any dual HOG setup.

Will I ever convert to dual? Possibly, but that's not a priority by any means considering I have confidence in the current braking setup.

That might be somewhat true, if you were also doubling the tire traction (which you are not).

In most of our street riding scenarios, traction is what limits your stopping power, not brake power (if your brakes are working properly).

I can lock the front tire with 2 fingers with my stock setup on my 13 SB.
