I took a white GT outfitted with Akropovic cans for a ride last Saturday...at Sandia BMW
Once underway...GT felt as light as my FJR and was easliy as manuverable up to around 90. The bike was easy to manuver...However around 90, the bike really wanted to go straight. Doing the little weave in the lane thing was hard to do at that speed. Not sure if its due to the weight, wheelbase, or a combination of things. Changing lanes and making turns was easy, but weaving the bike at that speed took more work. At slower speeds, it just fell whichever way I wanted it to go.
