Good point on the weight bias - I would also add the long wheelbase is a factor. My last bike was a Buell and I had to rely on the front brake for almost all of the braking ( the front would come right up on acceleration too.) When I first got my Harley I practiced hard braking to see what it would do and if the brakes were any good. I was impressed with how hard I could brake with the rear and now use it quite a bit for normal stopping. For panic stopping the back will lock up and be useless so I recommend still using front brake hard.

 

I've owned Harleys since the 1970s. My first one, a new FX1200, recommended in the owners manual that I use the rear brake for all normal braking, only using the front for heavy stops. Being European and having learned to ride on 'proper' bikes, I ignored that! My current Glide, also bought new, came with a larger and thicker rear rotor than up front, although the advice in the manual to use it over the front had been dropped. An Illinois State drivers guide I still have somewhere, given to me when hiring a Harley on one of my visits, advises other drivers that motorcycle riders often fall off - no wonder, you may well say! Those comments may help set the scene which you have recently joined, but over-use of your front brake, on this type of bike, may have similar consequences to over using the rear.

So while you have your view on the 'correct' way to use brakes, the old fashioned US habit of preferring the rear brake still prevails amongst some Harley riders to this day. I suggest that the truly correct way to ride your new dresser is between those two extremes! You are riding a long wheel-base vehicle, with a low centre of gravity compared with most brands, which is also darned heavy - even before you sit on it. You are plainly still adapting to your new ride, so start using the rear brake more and see how you get on.

I've been down the twin 13" front rotor route, with 6-pot calipers, and they were just great - for a short while. They are particularly good for riding through the Alps and other similar mountains, on steep hills, but in my experience they just don't seem to maintain their performance for very long before requiring maintenance, to restore their effectiveness. I've recently dropped them in favour of current H-D Brembos with EBC floating rotors and pads.

By all means look into improving your brakes, but there is a great deal more experience in here than with just one master tech!
