Just a follow up to ABS trick mentioned by @rickh123, this system basically crashed the ABS software. It works and I've done it. I tend to hold the front brake while the rear wheel spins, just to speed up the computer confusion. If you turn the engine off using the red kill switch, the ABS remains off, though your headlight stays on, so it is a short term use trick. I've done this quite a few times, so I can confirm that it works. If you turn the engine off with the key, you have to do the rear wheel trick. You can of course pull the fuse under the seat. (I'm not sure which one it is, but others will know). Neither of these techniques solve your exact request, but it is the easiest occasional solution. Some riders wire in switch to turn the ABS off, and that comes with good reports of success.
