Hello friends.


Im in the middle of a major renovation on my 2007 Ultra. Photos to come.


So heres what I have going on.


Im installing a 2015 Enforcer wheel on the front along with the brembo brakes, a racetech kit in the forks and black lowers.


All the posts say to remove the ABS bearing and install a non ABS bearing. My question is, why?


The standard bearing is .587" wide and the ABS bearing is .707 wide. I looked at the HD parts fische, and all the touring bikes from 09+ use the same center spacer. So, if you install the NON ABS bearing on one side, you would have to press it in .120" past flush as it used to be and the oter side is.


That considered, the Fische also shows that they all use the same outer spacer from 2009+ and shows no different part for NON ABS vs. ABS.


I bought the axle and outer spacers for a 2009 SG already.


So what about the bearing spacing? I have a .120" defficency in center sleeve to install the bearings flush as they were.....


Do I just go get another ABS bearing, press it in and fit the spacers to make sure were good?


Has someone put an Enforcer on a 2007 or earlier bike that has an exact parts list?


Sorry if im overthinking this, but it don't math out right in my mind. The axle number is all the same. What gives?


Thanks for info!

Change the abs bearing out for a non-abs one. The axle spacers make up the difference. Things will not line up right if you don't.

 

On an ABS bike the left side (sitting on the bike) axle spacer is actually the ABS pickup which is narrower than the axle spacer on the left of a non ABS bike. Thus,theoretically using an axle spacer the same width as the ABS pickup and leaving the ABS bearing in the wheel would work, but if you leave the ABS bearing and try to use the axle spacers off a non ABS bike the left side spacer will be too long.

Thus, most people put in a non ABS bearing instead of getting a spacer and machining it down or making one. I hope this makes sense.

 

That does make sense.


I just pressed in the non abs bearings, so im making headway.


I question I have that the service manual as well as extensive web searching has not yielded a good answer to is, why is 1 wheel spacer thicker on my 2007 non abs ultra? What in the front end is offset to require a wider spacer on one side?


I have done a lot of math with this.


If I add up both bearings, the center spacer and both outer spacers for my 2007 1" setup I get 8.306" or close too.


If I add up both non abs bearings, the center spacer and both outer spacers for the 25mm setup I get 8.420"


The difference between the 2 concerns me with using the non abs 25mm bearings and proper metric non abs spacers as many have done.


And, if I did just use the 25mm setup as others have, will the wheel be centered right on the bike?


I checked the bearings on my 07 wheel and they are both flush with the hub, and the hub measures symmetrical on both sides, hence I don't comprehend the spacer thickness difference.

Welcome to my nightmare just plain john I won't settle for anything less than perfection in my bike. Hence my overthinking and matching this.

 

I'll be watching. I'm looking for a wheel now.

 

A lot of what I have read from folks doing this, the final thickness of the stacks don't equate, which would cause problems with the forks in the long run. Unless im just stupid and overthinking this, or missing something.


That considered. Im trying to keep this with off the shelf parts that I don't have to machine to work. If I had to machine anything it would be the center spacer, then set the bearings into the wheel as needed to keep the spacer tight.


IDK. There is more than one way to skin a cat, I just want it perfect.

 

First, the outer spacer is not the same for ABS and non. The outer spacer is for the non ABS bearing. The ABS bearing uses the speed sensor to take up the rest of the spacing.
The two different wheels must have slightly different offsets. Most important is installing the left, primary side bearing first. It must be seated in the shallow pocket whether flush, recessed or sticking out. The other side has a deeper pocket, the inner spacer stops the bearing from being pressed in too far. This sets the rotor spacing. I wouldn't get too hung up on the numbers, I went and measured my old wheel spacers and got 8.360" vs your 8.306". Using all the 25mm stuff the wheel should bolt on and line up fine. I have a 2014 Enforcer wheel on my 2002 but I used all the 1" hardware.

 

Great info thanks
