I'm not positive. I believe it happened during racing a new Indian. I think it happened when shifting to fifth gear. I missed that shift and had to try again. It's happened to me before because of my heal being in the wrong place. It went into fifth, but when I came to a 45 mph curve running 120 or so I went to downshift and noticed the gear shifter was not connected and way out of position. So, I'm not positive, but I get pretty excited when racing this particular buddy of mine and I may have hit it too hard, but I believe it just happened because I've done this a hundred times or so. I have two R3T and one has over 30,000 miles and that bike has performed this kind of treatment more times than I can count. I ended up ordering a new one shifter and noticed the part has a superseded part number. So it may be Triumph may have had some problems with it and has redesigned it a little or has made it out of stronger material.
