Everyone is correct, bikes feel no lateral G forces while being ridden.
Sure, as long are you're sitting upright. Once you run out of ground clearance you have to hang off the inside of the turn; "one cheek or two?" Most sportbikes and dual-sports have plenty of clearance, but the "standards" I prefer often don't. With a rider and passenger hanging off in the twisties there's enough side load for the forks to do funny things; they're not really intended for that kind of load.
And I'm not even going to mention the sidecar and tricycle guys...

Cars have huge lateral G forces. Some of the tip over sensors are mechanical, if so drill a small hole and fill it up with silicone goo.
I actually added a Ford G-sensor/crash sensor to my RX-7. The GM '727 EFI system I'd cobbled onto the small block Ford used an oil pressure switch to cut fuel if the engine didn't start after a short period of cranking; after that, it ignored the oil pressure signal. (the 727 wasn't a particularly sophisticated ECM by modern standards) I visualized getting the car upside-down in a crash, perhaps knocked senseless, with the engine happily running inverted, which it could do for quite some time even without oil pressure, as the surge tank would keep it from running out of fuel immediately. The Ford "sensor" was just a ball, cup, and spring, and if you whacked it hard enough, the ball would shift to the side and break the circuit. It took a pretty powerful whack to unseat the ball. I mounted it on the console at the base of the shifter so I could reach it easily if I ever needed to reset it.
