    Today when riding aggressively chasing other sport bikes up the hill to Idlewild, California I noticed the traction control light flashing while cornering fairly hard. It did this most of the way up the hill while cornering. No flashing while going straight. Never had this happen before while on the same ride. I didn't notice any rear wheel slippage. Anyone else experience this before? I will look in the manual to see how to check the TC settings. I have never changed it.

    If the road is rough and the bike is under hard acceleration, the light will flash occasionally. Mine does this on the MGTC 1 setting when accelerating or cornering over rough pavement or over a noticeable bump in the road. That said all the way up the hill, I would suspect there may be an issue with the rebound settings on the shocks. The shock compresses but does not "push" the tire back to to pavement in time to prevent the tire from rotating while in the air, or spinning on the pavement, thus triggering the TC light.

    I think that simply means TC is working.

    Love that ride. Sounds like you may have bumped to MGC-2 from 1, that or the road surface was very cold, and as stated above, traction control was working full time. It is a 1.4L twin after all. ;)

    Agreed. It's showing the traction control working due the loss of traction (or wheel slippage).

    I have ridden that section of road before just as aggressively without the light flashing. It's a fairly smooth road with banked corners. I will check my TC settings to make sure it's not on 1. What's puzzling is that when it's flashing I'm not really hard on the gas.

    You want it on '1' not '2'. You haven't recently changed the rear tire have you? If yes, stock size or no?

    No I haven't changed the tires. Running Avon cobras stock size although the rear is at the end of its life. The sides are pretty well worn down. TC 1 ok.

    I haven't put on new tires yet. I've been running these tires for 7K miles without this issue.

    OK, all I'm trying to say is if you didn't do the Tire Calibration when you put the Avon on, it is likely the reason for your TC light.

    Recalibration is a pain in the butt. Travelling at a constant speed of 18.64 +/- 1.24 mph isn't that easy to achieve. You'll probably take several attempts to get it to accept the recalibration.

    Could it also be him riding on a worn tire?

    Yes, the tire is at the end of its life especially on the sides. I suspect that I was riding at the traction limit on the edges of the tire. I just got new tires to install, the same Avons I'm running now.

    Hey, I finally saw the TC light on while I was riding. I was a little concerned that may be a problem with ECU because it stayed on. Thought I may wired up something incorrectly when I helped my son install Todds fueling system upgrades (more about on the appropriate forum soon, all good).

    Turns out that if you take the battery out to replace the air filter MG forgets the MGCT settings and turns that little light on.

    AND resets the riding mode to Tourismo.

    Thanks to the forums, and the owners manual I was able set everything back to my version of normal, Veloce and TC-1.

    Checked the setting and somehow had changed the TC setting to 2. Changed it back to 1. Probably did it when I thought I was using the turn signal.
