My M900Sie has the "916" forks as standard and is fitted with higher risers as standard to raise the bars above the fork top adjusters.
It does this with the forks the standard 20mm above the yoke. (to the top of the fork top nut flange.)
Just before my last ride, I dropped the forks by 10 mm and I'm amazed at how nicely it handles now after riding it at the "standard" setting for 10 years.
The turn in is now much more confidence inspiring and its steady throughout all lean angles, holding a line beautifully and yet still willing to flick round manhole covers just like before. I even reduced my chicken strips a little more.
It just felt so wobbly after riding the Commando and Zero. It now feels much safer and I'm holding more corner speed too.
Only slight drawback is a bit more side stand lean, but that's fixable and I'm planning on fitting a centre stand anyway.
