Guys I have the xr caliper on mine, just be aware that it is a very very tight fit on the 2011 irons. Mine was installed by HD for warranty purposes but the caliper has worn a very small grove into the machined sides and worn a small edge off the caliper. It looks fine once installed but under riding conditions it does expand that tad.

To fix this you need to remove the caliper shave off the small edge and hit it with some Matt paint and the machined edges with some wet n dry.

Absolutely worth every cent....thanks Scouser for first bring this to our attention.

Did not have to modify mine at all on my Iron. Tho the clearance looks kinda tight, there is no problem, and they seem to be improving as they break in. Does give some dive to the front end , which I never noticed before........;0).

doe's anyone know if they are likely to fit a an 07 roadking--cheers Grim

I'm in.....

Yeah, I'm interested too

I was at peter stevens on Sat and asked about the XR calliper and braided line. They said it would be approx $900 to do. Group buy would be worth it if we can still do it.

Thanks Scouser. I might have to take you up on that offer for a carton of beer or a bottle of scotch or something.

I'm doing some research now to where is the best place to find the parts. I'll try and get a written quote from the stealers to compare.

Scouser ur a champ, I'll order them on Monday then. I'll keep you posted.

You might as well tell me what u drink as I'm bringing a bottle of something with me when we get around to doing it.

 

Slapster, I saw that but the dealer said they wont fit. Don't want to risk ordering it and then find out I'm stuck with it. I'm happy to pay a few extra $$ for something I know will fit especially when some friendly labour is around!

Does anyone know if this caliper would fit 2011 sporty custom? I believe it's the same front wheel, but not sure if the forks are the same width?

Shit Scouser I just realised its my niece & nephew's bday on sun.

Maybe the next sunday. I'll wait for your PM

Been ages since I've dropped in here. This thread is awesome to see! Love that the XR caliper fits on both the Iron and the 48.... shame it doesn't fit the bloody nightster LOL!
While I was in the US recently I was riding a sporty with the dual XR calipers- so, so, so nice. She stopped on a dime in such a wonderfully compliant manner. So yet again I'm thinking about a new front end on Nyx as I'd love the extra travel too, but for the moment I brought back the parts for a single VRod brembo conversion that I'm intending to get to once the rain sets in up here.

G'day guys
Hi scouser love the set up regarding the XR calipers thinking of doing the same with my 48 can't seem to find the M&M website to purchase the calipers any help would be appreciated
Cheers

Try your local harley dealer dillai. I paid around $220 for the caliper and $150 for the black braided line. My line was too long so had to have it shortened though.

Have just fitted the XR caliper (HD42943-08) to my 2012 Iron, all went well except it now has a scuff mark on the wheel spokes caused by the caliper casting rubbing on the wheel.  Fortunately I found the mark while in the garage before riding.

Going back over posts in this thread I noticed i'm not the first for this to have happen to.  So in the interest of sharing knowledge i'll try and post a few pics so people can get a clear idea of what to look out for when doing a self-install of the caliper.

By the way it's a HUGE improvement on braking and well worth the money.  Lighter action on the lever, better feel when braking, more predictable, ability to pull up quicker, brake later, more confidence etc.  I will be fitting a braided line and floating disc in due course.  For the moment I like to try things in stages and determine the difference as I go.

Part sourced from HH in Adelaide, list price $233.25, paid $209.95 with discount.  Picked up a bottle of DOT 4 brake fluid for $10.

It would have been a 1 long neck beer job, but because I had to file and re-check clearance it was 2 long necks.....

No special tools needed and no need for a dealer to do either, so anyone considering this as mentioned by others have a go and do it yourself.

Thanks to others for posting advice here, it has helped me a lot!

XR caliper (HD42943-08) on 2012 Iron

Showing rear where it had to be filed for clearance between the spoke and calliper

Tight tolerance between caliper and spoke 

Front view, I checked using feeler gauges the gap is actually around 0.68mm after filing the bottom section of the caliper and now doesn't rub

Showing the scuff mark that is unfortunately on each spoke, it the small horizontal line across the polished section of the spoke.  Best to check this before riding by pushing the bike on flat ground and listening for a scratching sound or ideally using feeler gauges before turning the wheel.

 

Handy info & pics, cheers IE. The caliper upgrade is def on my to-do list.

Slap.
