Looking at either converting a front 19 inch wheel to the rear, or relacing a spoke hub to a 19 inch wheel.
My bike is a 2018 1200 Iron with mag wheels. I can either get spoke wheels and have wheels relaced to oem hubs. Or see if there is a 9 spoke 19inch front mag that had dual disc that I can convert to the tear so it matchs the 9 spoke front mag I have on now. I just cant find a answer if there is a 19 inch 9 spoke mag wheel that uses 25 mm bearings for my bike. Any wheel gurus know?.

 

No ... There's no Current Design OE 9-spoke Dual Disc 19" Front wheels


The only Narrow-glide, Dual disc, 9-spoke 19" front wheel stopped in 1995 (in 96 they went to 13 spoke) and it was a Tapered Roller Bearing wheel (not a 2000-later Sealed Bearing)

And It would NOT be identical ...Just goo goo for some images

 

My 2006 and 2007 1200Rs have dual disc and 19inch front wheels which you can plainly see on the photo above. While my 2006 actually came with wire spokes I swapped them out for mags to get rid of the tubes. 2008 is when they went to 25mm axles

As far as I am aware, all of the 9 spoke 19" front wheels like those above will take dual disc. They have a plate that covers the holes for the other disc when on a bike without dual disc. Check your bike and look closely at the side without the disk and you should see there is a plate there covering the holes.

 

NOT on his New IRON ... Single disc only ... No provisions for a Right side Rotor

They are not like the older 9 and 13-spoke wheels

 

Ok Thanks for the info, looks like I need to swap my mags for a set of spoke wheels.

 

Obviously I was missing the 9 spoke as I have 13 spoke.
But he should be able to pick up a 13 spoke mag drilled for two discs. It may not have the powder coating that the new Irons have but otherwise it's the same wheel. Check the parts diagrams and you will see the cover plate listed on the Lows and Irons up to about 2015

 

He asked about his 2016-later 9-spoke "Mag" front wheel NOT 13-spoke

IF he wants to install a 19" 13-spoke in the REAR and his 9-spoke in the Front ... He Can
IF he wants to install a 19" 13-spoke in the FRONT and REAR ... He Can

But I think he is/was trying to Match his EXISTING Front Wheel, but to be used in the Rear

.

 

Hmm ... Maybe there's a misunderstanding on what whylee is trying to do...

He wants to take a 19" Front wheel, install a Pulley and Rotor (using Adapters) and then put it on the Rear ... Creating a "Tracker" bike

He would like it to match his 2016-later 9-spoke Front wheel, but he can't use another Front like his because it only has one rotor mounting surface

 

Thats what I was getting at, I guess a 13 spoke in the rear would not be to bad if there is a adaptor kit available. I just cant seem to find one listed yet for the newer bikes.

 

If you are referring to the wheel above there is no way of readily adapting that for twin rotors or a pulley. The casting needs a similar mounting flange to the rotor side. Take a look at your rear wheel.
