The torx screw for the battery strap is a security feature to compliment the optional alarm. No point in having an alarm if any git with an allen key (like the one found behind the unsectured side cover) or an appropriate sized screwdriver can disconnect the battery. Fewer people carry secrity torx drivers on them. If it really bothers you that much, get a hacksaw and cut a slot in the head for a normal screwdriver, replace it with a normal allen headed screw, or get a security torx driver.
Our bikes don't come with tool kits, the Speedmasters only come with an allen key so you can remove the seat and fit one of the optional ones. The Americas don't even have that.
