I have a 13 Street Bob with a 120R. I have never found it to have weak front brakes. Any HD that I have (22) with single rotors will lock the front brake with two fingers.
The limiting factor in braking is the front tire not the number of discs. Of course it takes less pressure to lock the front with dual discs and they will not heat up as fast under hard use like on a track. But they can not and will not stop the bike any faster than a single disc-period.
A well trained person can generate 0.9 G's of deceleration on any H-D cruiser with either system. There is a school in Calif. that does that training. The average student in that course starts out with 0.4 G's. Then at the end can do 0.9 G's.
I find it easier to modulate a single disc just due to the fact that it takes more pressure to achieve the force needed.

Most harleys i've rode usually starts braking till a point where you can lock the wheel, i've test rode some sport/naked bikes with brembos and dual discs and HOLYBALLS how those things stops in comparison with my dyna, the brake curve is smoother and the feeling is far better, I mean you can get shot out of the bike if you don't firmly hold the handlebar.

Inverted forks.
I beg to differ.
A properly setup bike with high quality dual discs and good suspension will stop WORLDS better than the average Harley. Anyone who's ever spent a fair amount of time on sport or performance bikes is generally appalled the first time they jump on a Harley and try to stop, and rightly so.
The whole Harley suspension/brake setup on most bikes is pure garbage. A proper setup doesn't just lock the front wheel faster, as some seem to believe. It provides the rider with way more feedback of what's actually happening between the bike and the road.
There's a reason pretty much every other motorcycle on the road has dual brakes (often Brembos), and a quality suspension. My old Dyna was like a Model T Ford compared to my Ducati, which can stop in an amazingly short distance from high speeds. If I tried that on my Dyna I would have been in a ditch for sure.
Most of us really enjoy swapping parts around and doing things to personalize a bike and make it into something special. But we should not be forced into replacing whole systems of the bike because they're unsafe and just generally rubbish. Harley doesn't do anything about it because they don't have to. They have a loyal customer base who willingly pays full price for a badly designed bike, then drops thousands more just making the bike ridable. In fact, they're counting on it.

How to you feel about touting a few guys who do not have the talent to design a major concept than sell a piece as their own? I know as I am the only person who designed, veraciously tested, than produced and brought to market that design. Now that is the truth.

The point is not locking the wheel, but the way the brakes goes till the point of the wheel being locked, and with this I mean the braking curve.
...with brembos and dual discs and HOLYBALLS how those things stops in comparison with my dyna, the brake curve is smoother and the feeling is far better, I mean you can get shot out of the bike if you don't firmly hold the handlebar.

See you all next month.

All parts are ordered except for the wheel. They are back ordered till December. Well I guess another month won't be to bad. Once the get the wheel, the shop thinks it will only take a day to assemble. They claim they are now doing about one a month converting single abs discs to dual. They get the parts from a harley dealer.
See you all next month.

No better here , it crossed my mind the same way when they came out with the first s. Tough choice considering the low rider you have now. Its looks like a great bike!

Well I have been complaining that without dual front rotors my 2013 Bob has very poor braking. Harley should be ashamed.
I finally found a local shop that claims it can convert to dual abs. A lot cheaper than buying a new Low Rider and setting it up. I love my Bob, and have it set up the way I want. It took me nearly 2 years of looking and installing. Now for the last step. Essentially I am converting to a LR, but at the time I purchased, they did not have the current model. The conversion will include a new wheel, disc,caliper, brake cylinder and possibly new fork. I am sure there is more.
I will be taking the bike into the shop in October. They seem very competent and knowledgable. But I still worry and hope they put their actions where their mouth is.
Will post the dealers name and results if it comes out well.
I would appreciate any thoughts and advise on the conversion.
