George,
Sitting at a light in neutral is one of the worst ideas anyone on a bike can have.
So if I see someone about to rear end me at the light, I boot it into the intersection and get crunched taking a leg? :grin No thanks, I'll take my chances with getting rear ended. After the first car pulls up behind you, you've got a buffer, but I agree it's that first one you gotta watch out for. And I don't throw it in neutral and stand down unless I'm approached [ it's happened twice with a problem developing ]. The first time I had to dump the bike and get to work [ and that PO'd me more than having to deal with the asshat, he took more pain for that than being an aggressive turd ]. The second time I just jumped off the bike with the stand down in neutral and went to work [ surprised the crap out of the guy I lept off the bike like I did which gave me a little advantage to join the party ]. I don't want to drop the bike if I don't have to, it really upsets me. :grin
Getting off the bike prior the pillion is a good trick. I would think INTENTIONALLY dumping the bike would be the only way to accomplish this quick enough to not leave one exposed to an attacker.
See above, with the stand down, just throw the leg over the seat on either side and use the bike as a barrier initially :thumsup
I have no idea how many miles I've put on bikes, but the first mile on one started in 1969 and with the exception of 3-4 years in between have been sitting on one since then. I haven't ridden near the miles you have though, perhaps a couple hundred thousand at best [ and I say that because the beemer had 89K+ on it when that one got crunched with me on board [ at least until I went over the handlebars and through the windshield :dunno ] so I'm thinking just a couple hundred K.
Keep that beast up on two wheels at all times :thumsup
