I use one and so do most people who race the Panigale. It puts your weight backwards when riding and makes it feel more like an a Ducati 1098 sort of position. Loads of people were having off throttle low sides on the Panigale when they first came out and these are credited with helping stop that. Ive had two off throttle low sides on the bikes without the tank extension and not had any problems since. I'm six foot and it feels good, just a bit further reach to the bars. Most of the racers are like dwarves and don't seem to have any issues
