I have 13" rotors up front and a Harley rear one, all floating. I don't agree that they are no use on a Harley, they are fine. From way back, over here in the UK, they have been regarded as one of the ways of sharpening up Harley braking, along with after-market pads and braided hoses. Not scientific, but certainly my experience.

 

Exactly! I don't do dull well. :-D

 

Just take off your old rotor and pour some seafoam on it.
That should shine it up nicely!!!!!!!!

 

Hmmmmm.......Hmmmmmm.........Hmmmmmm...........

I'll post the results!

 

I have floating rotors front and back and they dont rattle and work just fine. Also put Lyndal pads on that work just fine. GeessH..

 

where did you get the rear rotor from?

I'm in the process of grafting a 4 piston Harrison caliper onto the rear of my bike and need to get a floating rotor to suit otherwise there will be the inevitable shudder from less than 100% true fixed rear rotor

 

They don't rattle.

Do they help straighten up the unevenness of Harley's wheel machining or don't make for a better fit, when Harley use fixed calipers? Most folks I know replace warped STD disks with floating ones. I cannot see any disadvantage to doing so.

Let's face it, braking has historically been Harley's most negligent department. If folks like BMW etc all go for floating, I'm sure there's a good reason for it.

And if H-D don't, I am sure it only to maximizing profits by ensuring you have to buy a new and separate system after you've already paid them for one that does not work.

"More chrome, sir? ($500 for the same caliper but chromed) It'll really help our margins!"

Exactly what I was thinking.

 

Second most neglected! First is suspension.....

 

As I stated in my previous post , my money was spent on better calipers. Performance Machine , to be exact. I agree the factory calipers suck. The inevitable shudder from less than 100% true fixed rear rotor, that is mentioned, has never appeared on my bike, & I still run the stock, factory rotors with roughly 30,000 miles , on her , since installing the calipers. Big improvement over the stock units. Saved my *** , more than once, as I spend a lot of time in the Memphis, Tn. metro area, & people try to kill you in this city! Very thankful for the great set-up I have on a light Lowrider. Floating rotors may work for you. If so, great. I went with better calipers with factory rotors with great results. I can't see putting another $180-$200, per rotor to fix something that works great, in MY situation. And most folks I know , who upgrade their brakes, replace the calipers , & keep the rotors, unless they are scored pretty bad. Thats my opinion.
Ride Safe,
Harold

 

You mean $111.96 each.
