Unfortunately im not a big computer guy. So how do you customize TC? I like my ABS why would anybody mess with that? What did you set yours to?
Page 35 & page 45 & 47 in the owners handbook have more detail on what's available, but a quick how to for turning off the TC in Rider Mode.
Press the Home button, it's on RHS just out of sight under the cluster, round about where your thumb would be.
This brings you to the Main Menu
1st up is Riding Modes (press the joystick in to select this)
the Riding Modes opens
Ist Riding Mode is Rider, select this (press the joystick in)
Scroll down to TC & select.
You have the following levels of TC available to you for this mode,
Off = Off,
Rain = highest level of TC, (eg 75%)
Road = mid level TC, (eg 50%)
Sport = between Road & Off. (eg 25%)
Select which level you'd like & either back out but pressing the joystick left to bring you back to other modes so you can configure them, or just press the Home button, the same one we started with, which will return the display to the usual screen.
With this done, when you select Rider Mode, your TC will be off.
Page 47 details how you can temporarily turn TC off each time you start the bike, which is what Atomsplitter was saying above, but I think you want it off permanently.
