I contacted Spyball about getting the alarm in the states. This was their reply:
Thank you for your e-mail and the interest showed in Spyball products.
At the moment, we are sorry to comunicate that we do not offer our
motorcycle alarm systems in the USA, because the American frequency is
different from the European one. We trust, however, that our existing
contacts with a distributor and several japanese importers might turn into
possible co-operations in the future.
Best regards,
