Default ABS module removed??

The ABS module was removed from my 2010 RK which I purchased used about 1 yr ago.
The way it is now the brake system works perfectly.
But why would previous owner do that??
And I have no way to contact hm to ask.

Are you sure, or was it a option that year?

If they did remove maybe failed and didn't want to spend money. Not sure how that works on bike. Easy on auto

It most likely choked and puked.
Been a number of them that have locked up and left a person the a hard pedal or lever.
Along with no brakes applying to one or the other.
Haven't heard of one locking up both at the same time ___ yet

Lots of threads on it.

There were backorders on the ABS modules for a few years. He also may have just decided to not replace it due to the cost, they're pricey.

It had ABS, you can see where the brake lines are bypassed and can see the ABS connector plug.

If he has abs there would be spacers on axle I believe. Is it possible connector you are showing was for options?

But as said, might have been expensive to fix.

I wouldnt rule out some old guy removing perfectly good abs either cause it upset him

1. Ref: 8 in the diagram below; 40649-08; ABS ELEC-CONTROLLER(SERV UNIT) Price: $687.38 and Ref 11; 48343-09A; CONTROL UNIT,ABS HYDR,SERVICE,FLT; This part replaces 48343-09; Price: $734.99
2. As stated there were problems with the ABS Freezing up if not flushed and cycled per the service manual every 2 years or more if the moisture content was high in the fluid.
3. A recall was issued, see: https://www.hdforums.com/articles/ha...ty-abs-brakes/
4. Unfortunately, problems with ABS technology have plagued Harley-Davidson motorcycles in recent years. The brand issued a recall in January to ensure 2008-2011 Touring models received a critical brake fluid replacement. And now, they’re urging owners to bring their motorcycles in for service and repairs.
5. The recall affects 175,000 motorcycles in the U.S. and 250,000 worldwide to fix a problem that could lead to sudden brake failure. In the recall, Harley-Davidson states that a faulty ABS module and/or neglected maintenance can lead to caliper failure. “This condition is associated with delayed or neglected brake fluid maintenance as specified in the owner’s manual,” said Carolyn Duranowski, director of marketing at Oakland Harley-Davidson. “Harley-Davidson is offering the remedy fluid flush free of charge to all motorcycles within the recall population, regardless of their maintenance history.”
6. You can put your VIN in here to see if the recall was ever addressed: https://www.harley-davidson.com/us/e...e-recalls.html
7. Looks like the previous owner did a good job with the bypass.





NOTE:
The above information, while credible, is worth what you paid for it and should not be considered gospel.
Do due diligence, research and have a H-D Field Service Manual before working on your bike.
You will probably have many opinions and suggestions presented; make sure you research the person providing the helpful information as there are some who provide good information that is useful and some who speak out of other orifices with gibberish. You will figure out this quickly.

When the HCU fails on my 2008 Ultra, I lose brakes and the lever is locked even when the bike is off. (Mine seems to be a front brake only issue)

Funny I just saw a video on you tube of a guy that had a locked up front brake lever 0n a 2008 Roadglide.
He did just what I see in your pics and it looks like the same parts he sourced from O'Riellys auto to connect the banjo bolts from the front to the back. Basically jumped out the ABS. Now I'm sure you must have some TDC codes since the wiring is unplugged.
