So it’s 50% throttle, not related to rpm? You haven’t had the first service? If you did, there’s nothing in the tune in sport mode that would keep you from doing 0-60 in 3 sec. It sounds like you’re hitting a limiter but not the rev limiter but even if Triumph has a restriction during the break-in period, it shouldn’t be there after.i do, it just shuts throttle down by itself.
