I've recently upgraded the brakes on my 916sps to 19mm radial master cylinder and new P4 calipers. This was a Ducati upgrade kit which also included two clip ons and new reservoir, etc. .....what a difference it has made. It's like learning to ride a new bike and last week, whilst on my 996, I could n't believe how dreadful the brakes seemed in comparision. I would wholeheartedly recommend the upgrade kit.
