oh , too far to ship anyways . assumed you were in the us for some reason.....well , thanks anyways !
OK lets talk physics:
if you look at the angle the stand is at when down, in relation to the bike, it as at barely over 90 degrees to the axis of the bike. With most other bikes, the angle is more like 120 degrees. this means that even when the bike is on a slight down slope, in order to roll off the stand, the stand tries to lift the bike slightly. The weight of the bike prevents this, so the bike does not fall over!. With the Haysabusa, the bike does not have to be lifted at all in order to roll forward and fall off it's stand, which is why it happens so frequently.
It hasn't happened to me, either, but I'm not so smug as to think it could never happen!!

Well im sure glad that im not the only cabbage around these parts. I can ship the stabilisers worldwide (and throw in a free modded airbox!).
Beam me up Scotty...

DaveD has it right.
Here is a simple demo.
Place the bike on its sidestand on level ground.
Put it in neutral.
Grab the handlebars firmly and start pushing the bike forward slowly while keeping your eye on the sidestand pad (the part that comes in contact with the ground).
What you will notice is that the sidestand starts to rotate back (retract) as soon as the bike starts to move forward, and you will notice that there is no resistance to the forward motion of the bike. A well designed sidestand will offer resistance before it starts to retract.

Sorry to hear about it, I'm sure the new plastic will be especially shiny. Anyway, I've been doing the:
1st gear roll forward to compression, retract stand, turn bars, keep pushing forward set down thing without a hitch.
One time I had it in gear, but didn't roll all the way forward, I came out with the stand beyond 90 backwards but still holding by the engine compression.
It has become habit, just part of my routine along with disc lock removal etc. Hope your bike gets better soon, like everyone said your not alone...you COULD always try and clone the TBR "Rodan"...who needs plastic?...

I've covered many thousands of miles a year over many years and have never have a bike fall off the sidestand - until my Busa.
I normally put the Busa in gear and roll forward but it was dark and the battery a little weak. So I had to keep the engine running and have the headlight on so open my garage, the surface is a little rough.
I did put the bike on the stand as described below and even kicked the stand forward to double check there was no slack once I got off the bike.
I've never taken any special care with any other bike other than the usual place the bike on the stand on right lock then swival the bars left once on the stand to force the bike back against the stand.
I do believe the Busa has a suspect stand.
My sidestand off caused a punctured alternator cover (£43) and no other damage.

Dangermouse,
How come you got away with so little damage? Surely there was some marks somewhere, like on the exhaust perhaps, or mirror?

For such a mod happy group as .org it puzzles me why there is so much antagonism toward a simple mod that could save you some grief down the road and will certainly make your bike more stable anytime it is on the sidestand.
There is nothing wrong with putting your busa in gear and rolling it against compression every time you park it on the sidestand. And, there is nothing wrong with modifying your sidestand so you don't have to go through this procedure everytime you park on what appears to level ground.
Even for those cautious (and evidently superior) riders that always put it in gear and roll it forward, the mod offers insurance against forgetting once in a while, or having someone else who doesn't know the drill park your bike (friend, wife, mechanic etc.).
I don't think calling people stupid or cabbages adds much to the discussion.
The mod won't shave tenths off your quarter mile or help you whip a ZX12, but it will give you some peace of mind and maybe save you a few hundred damage repair bucks.

Okay, I've read this happening over and over. What I make sure of when I park my bike is that if there is an uneven grade, the bike is parked with the rear end heading down the grade. If it rolls at all while in gear it rolls backwards keeping the side stand in the locked position. I also have a question for the guys that this has happened to. Have you lowered your bikes with no changes to the side stand? If so, this reduces the amount of weight that sits on the side stand keeping the bike place.
I haven't had this happen yet, even when the bike happened to be in neutral while I was cleaning, bumping into or my wife was climbing on, it.
I do agree that the side stand angle needs to be adjusted compared to other bikes I've had. I also agree with J.C. and that the center-stand is probably the way to go. (I'll get one eventually)

For yu gys still pondering this sidestand issue. Take a high speed die grinder and grind a little off the sidestand stop to allow the sidestand to travel a little further forward. Then if you have to work on it without the aid of a centerstand or such, just take a bungee cord and wrap the front brake lever tight. Now your n sur ence co will breath a sigh of relief.

mm1, I was lucky the bike fell into a bunch of over grown bushes, these cushioned the fall, there were very minor scratches that polished out, the alternator cover obviously hit something solid!
The exhausts are cheapo scorpions and servived without harm.

FYI My bike runs standard ride height.
