Thinking about gettingatleast getting the front floating rotorfor the Nightster. They do look alot nicer but I am more interested inwhether they improve the braking.

 

Floating rotors will improve braking IF you are frequently applying repeated hard braking pressure to the discs. Their design is to help dissipate the heat from stopping. Personally, I wouldn't waste the money on a road bike unless all you do is ride The Dragon and constantly keep the brake on.

 

I found the stock single disc brake system on my 1200L is more than enough for me, I downshift more than braking, it could be just me

 

The only to really improve braking is to increase the swept area of the pad to disk surface, that can be done by adding aftermarket four piston calipers with larger brake pads or adding a second disk brake such as the 883R or 1200R has.
As thumper says the floating disk is for competion use where you are heavy on the brakes 10-15 times per lap, they cool faster between corners to reduce heat fade.

 

My 103inch FXDXT is only about 20lbs more than a rubber sporty and I've got triple floating composite Lyndals and braided lines. Over the same road with the stock triple discs there is a dramatic difference in braking.....the road is in the picture.....braking and handling improvements usually don't "look" like much for the price, but I think they help make a more capable machine.

i put hawg halter 6 piston calipers with true floating brake tech rotors, nice difference for a single setup, also used ferodo sintered pads, bought from charleys harley at a discount, ask for jenny in parts she is sharp
