What is the offset in the touring wheel? The reason for the question is that I have completed the install of a '10 FLHX front wheel on the rear of my '02 FLHT and the offset, by rough measurement, is mas o menos .375" to the left (primary) side. I plan to run a 150/70 tire on this wheel (not mounted yet) and will be replacing the OEM pulley/belt with the narrow pulley/belt. Just wondering if I need to do the extra work to move the wheel to the right; more to the center? I believe all will fit up nicely but would like to know the touring rear wheel offset at it comes from the factory. Does anyone know?

 

I measured mine to see how far over I needed to be & changed spacers according to that. Be sure to keep an eye on the brake rotor as well, I had mine trimmed to move it over as well.

Thanks; I understand wheel spacing, caliper rotor alignment, etc. Have mounted a '10 18" Airstrke to replace the OEM 16" front on the old FL; have replace the 21"x 2.15" front on my Deuce with a Breakout 21x3.5" wheel. I am curious about the factory offset on the touring models, i.e., is it standard or does it vary from model to model. The photo below clearly shows that there is an offset to the left on my '02 FLHT. Hard to tell from the photo but I would guess the offset is .25" to the left (primary) side; not much clearance between tire and fender and the fender clearance will be the controlling factor over the maximum tire size I can fit under. The 150 will be about .50" wider than the 140, so I will need at least .25" of additional clearance between fender and tire. But if the new wheel is not offset to the left a bit more than the stock offset, the 150 tire fitment will be to tight or will not clear.



I am thinking I should shave the caliper and center the wheel but still curious what other see in the rear wheel offset in the pre '09 models before the frame and tire size change. Apparently, no one knows.

 

That was the way my 99 Ultra was. I moved it over to center it & have found no problems, have 8K since I did it.

My bike (in sig.) has stock wheel and spacers. It is centered in the fender and a 160 width tire fits.

 

IIRC, the '07 touring bikes had wider fenders; not sure. I know that the fender clearance appears to be the controlling issue for tire size. Pretty sure I could get a 160 in there with no belt/pulley clearance issues but doubtful that a 160 would clear the fender on the left side, eve with the wheel centered. Haven't given up yet though.

 

I find the easiest method is to cut your own spacers as required and center the caliper on the rotor at the same time keeping the entire assembly centered in the frame. It is just common sense with a little trial and error. The limiting factor in your case will be the rear fender.
I used the 180 rear tire along with a '10 Ultra wheel and cushdrive assembly on my '07 FLHP. I widened the swingarm but without the cushdrive and using an aftermarket wheel, only the fender would have needed modding or an aftermarket one used.

It really does become obvious what needs to be done once you get into it. Just buy a length of spacer stock. If you don't have a lathe you can cut it with a good hacksaw or cutoff saw and trim with a grinder. Don't be afraid to mill some off the caliper to get it centered on the rotor. I have been using my '07 caliper designed for the 1" axle on the 2009up 25mm axle for years now with no problems. Good luck!

 

My fender is 7" wide. I had to deflate the tire so I could get the wheel (stock width) and caliper into the swing arm, it was a PITA. Once in, there was plenty of room in the fender.

 

Also a 160 on the stock wheel is squeezed on and runs a little narrower than it would on a wider rim. Think it would fit with a wider wheel, once you got all the components in the swing arm and up in the fender. Wouldn't be a fun job.

 

Agree completely on the fender controlling the rear tire size. I see the 150mm tire fitting comfortably with the wheel centered and replacing the OEM belt/pulley with the later narros belt and pulley; a 160 might fit but not sure that a 160/70/18 rear exists.

I will have the caliper machined; check me out on the procedure though. I am having trouble with the geometry and am confused on what to cut and what to lengthen; just not sure.

I was also concerned about how critical is is for the rear tire to run on the same centerline as the front tire but have come to the conclusion that it is not that critical. I am pretty sure that the front/rear tires on my Deuce do not run on the same centerline.

Thanks for the feedback.
