FXBB and FXLR owners.
We've found the owners manual has the front tyre pressure for these bikes to be a little low at 30 , we've been running 36-38 depending on rider weight and getting great rider feedback. Myself I find tip in and mid corner with the higher pressure a much better feel and ride, the FXBB I've been riding has really benefited from raising the tyre pressure to 37 or 38 ,. it's the Sportster of the modern Softies and really feels better with the front up at around those figures.. . We had so many front tyre sets cupping and I've also noticed it on the internet too.Cupping is too soft suspension or tyre pressure or both , and as most who cupped were at the manuals suggested pressure it took us a while to work it out.. Front tyres inflated to the 30 lbs or even a little more all showed cupping. The rear is close but if you're a larger individual you can go higher. When you guys go back out as Winter fades this tip might be a good thing too as pressures sometimes don't come up as much as they should when it's cold. This is just a mention to you guys, just what we've found to be better . How you set your bike up is on you.
Peace, ride safe (but fast).

I have just over 4K miles on my FXBB and Ive been running 32 psi in the front since I purchased it new. My front tire is cupped to the point I will be replacing it soon. I ride a fair amount of twisties spiritedly and thought that may be the reason for the cupping. Thanks for the input, I will up pressure by 5 psi with a freshie mounted up and see how it holds.

I'll change to 36 front and keep 40 rear.

I've played with the front pressure some. I think the lower pressure may be specified to add a little damping to the front end. If I run it higher, I get a slight no hands wiggle in the front end at 45mph. I know, I know, steering stem bearings or tire balance. But the pressure also plays into it. FXLR has a pronounced rear weight bias, so maybe the 30 lbs in the front 19" is correct. PS, mine is ready for replacement 9000 miles not cupped at all.

After trying 36# in the front, I thought the ride got rough.

thanks for the tip ... I'd been finding the ride a bit 'odd' compared to my old Dyna, pushing the pressure up a bit on the FXBB front has helped (except the other day when thanks to Google Maps I ended up on a nasty unsealed stretch!) - initially I was finding it hard to trust the tires but this has stabilised things a bit especially around the 50-60kph mark
a lot of the 'odd' might be getting used to the road surfaces here in Australia, very different feel from the tarmac than back in Seattle (possibly something to do with the temperature!) especially the road markings which seem super slippery
