Actually my biggest bitch about Harley specifically is if I am out fanging it on my Jappa thinking I'm doing really well and some arse on FXRSSST is keeping up with me..............
I blame tyre pressures ...............

Dave is on the money, you are clearly not understanding the principles I'm afraid.
To give this some context, we'll go to yet another of the silly things I've done on a race track. Bike was an FZR750, racing it in post classics. Unfortunately it had one warped brake rotor, and would get quite interesting under heavy brakes. So I took the bent one off, and ran with just the other.
Could brake harder and deeper than ever before on the bike. The only down side, was that it literally melted the disk. The trailing edge of every vent hole in the disk, was very thin and the material dragged back to the leading edge of the next hole.
Still got the disk, I'm quite proud of it. Stupid Buel disks are notorious for doing the exact same thing.
So it's not about braking power mmmkay, it's about maintaining that power without things getting too hot.
It's no good putting another disc/caliper of the front of the bikes with the 21" front wheel. The tyre's contact patch is tiny and very easy to overwhelm. The reasonably large floating disc and big caliper they have on 'em is just fine. And others have said...you can use a shitload of rear brake too to help haul 'em up. They're all ABS equipped too. So youi can just jump on everything. You'd be surprised how quickly you can stop the things.
Ah, didn't know that, worth remembering. I thought (= assumed) twin discs would be better because of the ability of twin discs to cool faster given the doubled area for the same braking effect. I do prefer the twin setup but it's good to know that if I rent a single-disc during my travels I'm not worse off for brakes.
Isn't that what I said :-)
Less likelihood of fluid boiling too.
I had a fairly long talk with Erik Buell about it and heat outcomes in the ZTL perimeter brakes - at a bar in outback Victoria. That was a 'pinch me' moment.
Anyway, Wide Glide doesn't go hard enough for heat dissipation to be the issue and the brakes are fine.
I did 150km on a new Heritage with a single front stopper yesterday. It needed more lever effort than the Widey, but there was still nothing at all wrong with the brakes. Particularly for a 360kg vehicle.
If you put 'savage' stoppers like a sportsbike on them I bet the old timers would tuck them for sure.
Yep moot point Al, it's the golden rule when making cars more powerful. more power = more brakes. My ole Suzuki 1500 cruiser had the single front disk with only singe pot caliper, was scary compared with the GSX 1200Y I was used to pootling around. However a mates honda little 750 cruiser has a sinlge disk front, works a treat. We finally dumped the Suzie for a 2000cc Kawasaki cruiser thats near on 400KG and has a twin disk front end, I'm amazed how well the behemouth pulls up. So set up is critical I suppose to get efficient braking. Horses for courses stuff eh.
Dave, that Harley looks awesome, look forward to seeing the write up. Have to say, those exhausts look like copies of Vance and Haynes products, shame HD didn't lift them up and inch or two to improve clearance eh. Cheers Ando
Thanks. Article is done and dispatched. Ride impressions and a bit of the model's history.
I have a new Fat Boy with my Heavy Duty magazine hat on this week.
Been chalking up some very enjoyable miles on that too.
