I would like to change the angle on my Mille from 2001. I would like to push the ends a bit forward to get more front lean and less pressure to the outer parts of my palms.

There is a clamp, holding on to the front fork, and also a screw that securs the clamp won't turn unintendedly.

My question is: Will the clamp be enough on it's own to secure the angle even during hard braking and a lot of pressure on the clip-ons?

Thanks,

Tommy

What you may find though is you don't have much scope for pushing them forwards before they start hitting the fairing and dash at full lock. You can do a couple of things to help here:

1. Reduce the steering lock (https://www.apriliaforum.com/forums/showthread.php?358825-How-much-do-you-raise-the-rear-ride-height-for-track&p=4694846&viewfull=1#post4694846). I did this by fixing a cable tie to the stock lockstops. Small difference in lockstop thickness, but good difference in steering lock. You can also get adjustable lockstops from I think red rat or AP workshops.

2. Shift the fuse and relay boxes back a bit. People have done fancy things with modifying the front subframe for this. But I found all I needed to do was loosen the bottom screw and sort of wedge the fuse box behind it. Then the limiting factor is no longer the plastic fuse box and is instead the subframe. Not much more room, but enough to make a good difference.

All aftermarket or race clip ons do not have the small screw you mention so again as mentioned the clamps are what secures the clip ons to the leg. The screw just assists with locations the same angles 

I know there is not much place to shift the clip-ons a bit forward, about one centimeter or so, but small adjustments will do atleast some kind of release for the outher parts of my palms.

I've got aftermarket clipons now with 2 bolts on each fork leg. But even the stock ones which have a single bolt to the fork leg were perfectly fine for me. 

If you do what I said with moving the fuse boxes (or I guess even if you don't), I found you can get them pretty close to symmetrical just by setting them so that at full lock they have a couple mm clearance. Assuming your frame and subframe is straight, which it should be really. It's close enough for government work I think as even if they are slightly uneven, you adapt very quickly to it. 

I found the same thing as you with pressure on the outsides of my palms with the stock clipons. Like they point far back but my hand is stubborn and holds them at the angle it feels most comfortable. I was able to push them forward enough to get my hands more flat on the grips. 

I also dropped the clipons a bit down the fork leg to help me get more weight over the front. Though due to the air ducts I was only able to get so far.. 

At times I look at other bikes in the paddock and am jealous for how much space they have. The front ends of these bikes are pretty cluttered compared to most modern sport bikes.
