It was something internal Hellfire because they pulled the motor out of my bike to get to it. It was a warranty job my bike wasn't selecting neutral and sometimes was very hard to shift gears at all.I took it to the dealer they contacted triumph and Triumph Australia said to replace it .
Something to do with the part being put together wrong from factory or something.
I dont think it was a common fault but did happen from time to time .
Sorry i cant identify the exact part Hellfire im not sure of the exact part i just know it was internal. They had my bike for a couple of days and they referred to the part as the gear actuator . It definatly wasn't the gear position sensor.
