Doubtful, since no such regulation exists and other makes being shipped to the U.S. don't have such a second switch with their keyless ignitions. The U.S. only requires the normal kill switch on the handlebar. But it's possible that there used to be a regulation years ago and Triumph never got the memo, or maybe there's a single state somewhere and other makes only provide it when shipping to that state. Or maybe it's a Canadian regulation, and they don't feel like shipping two configurations for the US/Canadian market.
