I have never had a motorcycle TPMS be 100% accurate. Their job (IMO) is to warn of rapid (over the course of the day) or sudden (puncture) air loss. Mine served its purpose well, with the red triangle warning when I picked up a drywall screw on the slab in the middle of the NV desert (on an Iron Butt ride).
Took less than a minute to lose ALL air pressure, but I was pulled over before it was all gone.
FYI, my current TPMS on my '13 GTL is one pound low.
