V7II Safety (?) Feature

I picked up a nail in my rear tire today. The fuel was cut and the TCS light was flashing at me. Not realizing I had a flat, I sat by the side of the road, revved the engine and thought everything was OK. As soon as I tried to ride off, the fuel was cut again. That's when I discovered my flat. A bit of a surprise.

That is pretty cool. I did not know the traction control would do that. Good to know!
 
John, very unfortunate day.. but good to know. I wonder what the system will do if the tire goes flat either quickly or slowly while riding(?).

16d nail. I didn't have a chance. Nice and shiny, though. Definitely new construction. Some dweeb bent it and threw it away. I picked it up for him.
 
There seems to be a lot of hostility about this on the "other" Moto Guzzi forum. Folks are jumping to all sorts of unjustified conclusions about this newly discovered "danger" of TC. In my experience with the TC on my V7II, it doesn't abruptly cut the fuel, it just throttles down to try to prevent the rear wheel from spinning much faster than the front wheel. On startup, it doesn't even engage until the bike is going about 3 mph or so. And, you can always manually disengage it pretty easily. I guess ignorance breeds fear.

As of 3/21, the thread on the "other" site seems to have been deleted.

Yup. The internet is full of them. I just see it as entertainment now. The same kind of discussion happens around ABS. If you don't like the features, don't buy the bike. Still plenty of bike out their with neither feature. Or like SIB said, turn them off

Curious to know why it actually did what it did. Guessing since the diameter of the rear tire changed from the flat the perceived speed of the rear tire to the front tire changed and engaged the TC. Unless the rear rim was spinning in the tire?? Wonder if it would work with the front tire.

Either way, nice accidental feature of the system. Would be good to know at what PSI the difference in speed is picked up by the system.

Off topic here... but here's my experience (recognizing I'm outside of the norm in my riding style), but the TC does in fact kill the throttle enough that I've nearly ended up sitting on the tank when I pegged the throttle going over some ripples in the pavement a few times when I first got the bike. Additionally, I live at the top of fairly steep dirt/gravel drive and the TC makes the bike nearly not move when turned on, but I just turn it off the minute I get on the bike now, of course.
It has also wreaked a little havoc on some of the bikes I've done performance work to, as people report back that the bike is having a massive fueling issue, but of course is gone when I tell them to turn off TC.
On topic... it's a pretty nice feature for newer riders, especially the flat tire scenario.
 
I'm with Todd on this as I've had similar experiences with my bike.
TC is a great idea but I think the TC on the v7 seems a bit to sensitive so I always turn it off.
