Just curious, has anyone driven their gmt900 to 140 mph? How does it handle?

I've had mine up to 132 handles great, had my gmt800 up to 137 also handled fine, the faster you go the smoother it gets :p
I had my 2007 north of 110mph, but that was when I was trying to keep up with a LifeFlight helicopter that had my son, who was 5 at the time, in it. Only time ever that my wife asked if I could go any faster. Not sure exactly how far north I got. Rode pretty smooth as I recall.

with the 3.42 these things top out at about 137, some claim they have reached 140 if they did they must have had a good long straight away, takes well over a mile to get up there in the top end and that's assuming the limiter is disabled, mine is set for like 240 of course it will never ever reach that, lol
