Careful RG a member on here, kinda from your neighborhood had his XS650 bobber stolen. Regina IIRC.
Some kid with a chooper project going may WANT an xs650 parts donor more than a late model sport bike. I have a had a lot of stuff stolen over the years, car, lawn mower, water heater, the wheels off my older chevy truck, really, came out in the morning, the truck was sitting on the brake disks, near countless power tools. But never have had a motorcycle, jacket, helmet or even gloves taken. So far anyways, life goes on. I have gotten bikes with locked up wheels in my van several times, with the aid of the seller. One was a KZ1300 that weighed near double an XS650. Ramp is handy, but not really needed by a couple of clever young bucks.
two moving dollies to wheel it to a convenient working location would do it. Armed with a battery angle grinder, not much is impervious. Automotive cat converter thefts are dirt common in some areas.
Neighbor here had all the tools stolen out of a long new house construction project THREE times. Third time they had 'em on video. Tracked them to a pole shed in Iowa it was filled with tools from a three state area. We had three semi loads of cheese stolen here in Wisconsin. The empty trailers were found later.
