Single front brake questions

It looks like PM uses the same caliper for 11.5" and 11.8" rotors. Your 07 has 11.5 rotors. A 13" caliper carries a different part number and is different so that it can with a larger diameter 13" rotor. There is also a bracket made that will allow your stock caliper to work with a 13" rotor. This is made by Rc Components.

I understand your concern and have done my research. I'm not trying to start a thread for a debate on why one should or shouldn't go this route. There are plenty of those out there and i just got done reading most of them. I know many think it is stupid but I'm not one of them. Single brake set ups have been run with much success for many many years. If I can squeeze them and lock them up with a single how much more stopping power do I need? The benefits are looks, reliability, and ease of cleaning and oh yeah and looks!

Just curious, if that bracket that allows you to move your stock caliper for use the 13" rotor would also work as a bracket for moving the six piston caliper from hog, PM, or jaybrake that works with the 11.5? Also I'm beginning to notice that the cost or rotors nearly triples when you go up to a 13". I am a cheap sob and am wanting to try and get the best of both worlds which I know is probably not possible. But if I can buy a six piston caliper and get by for a while running my 11.5 it would buy me some time to save $400 on a 13" rotor.

The bracket for the 13" rotor will not work in the opposite fashion unfortunately. I'm not sure what rotors you are looking at that are $100 but that is very inexpensive as far as rotors are concerned. If I were to do this swap on my bike I'd do the 13" but I would not do this to my daily rider. I'd rather stop on time than look cool in rush hour Los Angeles traffic. Plenty of customers have done this swap with stock size rotors and calipers without issue but I put more stock in my brakes in big city daily riding.
On the 2000-2007 models you are going to need a 9/16 bore master cylinder as well and don't forget the new brake line. The stock line is all 1 piece so you cannot simply unscrew the portion you are not using. On 2008 and newer models the stock master cylinder works fine as it is a different bore.
There are a lot of ways to do this but remember, your brakes are what stop you when someone cuts in front of you unexpectedly. I have no stake in this either way, but it only makes logical sense to run a dual disc setup on a touring bike as it is a very heavy bike with a lot of weight on the front end.
If I had a second bike that I only rode on weekends I'd do this as the look is much cleaner, but it is what it is.
