I suspect that designing hardware specific to enhancing the safety of
brakestands being performed elsewhere than on the dragstrip is more
effort than is warranted given that the bike's mission is drag racing
and the additional interlocks, etc. would quite possibly interfere with
reliable operation on the strip.
I think the solution for public displays may be as simple as ensuring
that there is adequate clear space in front of any waterbox to allow
safely stopping the bike should it launch.
I haven't had the pleasure of doing a brakestand on a bike of this HP,
but my experience with other bikes is that the rider stands, applies the
front brake, and leans on the handlebars which compresses the front
forks and transfers some weight off the rear wheel just as the throttle
is rolled on. During the brakestand the front forks remain compressed,
so a switch that cuts off the controller if the forks extend normally
could also work, however, like any of the other approaches, it would
just be one more bit of wiring that could interfere with the bike's
normal operation at the strip.
