No disrespect, but I disagree with the above. Aftermarket (race) bodywork does not include cutouts for the kick stand for a simple and obvious reason. Racing organizations disallow them. And it's very easy to remove material to include them, but realistically impossible to add material back for those that don't want the cutouts. It has absolutely nothing whatsoever to do with the ability to hold fluids. As a matter of pure fact, the depth of the cutout for the stand relief on two of my bikes that still have stands (one does not), it is STILL "taller" in that area after having material cutout, than in other areas of the belly pan - INCLUDING the very back. Further, you really don't need to cut much out, and it has absolutely nothing to do with any of the fastening locations - at least on any bike I've ever seen. Motoamerica requires the pan to be at least 70mm tall. That's only 2 3/4". Still passes with flying colors.
Two more points. OEM manufacturers deal with millions of bikes and millions of riders, and have to deal with NHTSA and other governing bodies. How many accidents on the road have been caused by kickstands improperly coming down? It's not even a measurable statistic. 60mph is just as dangerous as 150mph on public roads. The roads are bumpier, with pot holes, etc. Still not an issue. Believe me, if it really were a safety issue, there would be a "lock" preventing it from coming down just to protect manufacturers from litigation. There isn't.
I bought my first brand new street bike (750) in 1979 when I got my motorcycle license. Been riding ever since. I've never, ever seen a side stand come down during riding other than on a real POS that wasn't maintained and was missing the spring or something. Even my KTM dirt bike has a side stand, and it doesn't come down either by accident. When you're going through terrain as bumpy and aggressive on your track/race bike as I am on the KTM, the side stand is the least or your worries - you're already screwed
The bottom line here is that it's really a personal decision, based on interpretation of your own needs and concerns, but NOT a safety issue. I personally find this more of the same thing that causes us all to spend a gazillion dollars on high end race equipment (I'm not immune to that) and then sheepishly watch as YCRS coaches like EZ and Kyle come past us on bone stock FZ's.
BTW: I'm a bit fussy about my bike. I trimmed my belly pan on the R1 right after getting it from Swenson. You would never be able to tell I did it and it wasn't that way to begin with if you didn't have another R1 with Sharkskinz sitting right next to it. Do it right and seal it, and it looks factory.
