With this bike, if you just want to "cruise", leave TC on. If you want to use its power, then TC has to be off. There is no in between or levels or I just haven't read the user manual. With TC on, even a quicker launch from the traffic lights and TC cuts in and bogs you down. Has happened to me so many times. So sensitive. And it is official, even though you won't read, experienced testers/journos did 2-3 clutches on the Journo ride day here in Australia yet none reported that in their articles. I only found out from Triumph distributer here after the event and that was confirmed by a friend who was one of the testers on the day. So even experienced guys who test bikes for a living were destroying the clutches on their first time on it. How? **** knows! I'd love to know the science behind it also and why this doesn't seem to happen to other bikes?
