I think it is very common. I almost always hold the brake on start up. Not as much with the new color display since it starts in PA 0. But the “old display” ( original one that came on the Pace 500) started in PA 1 so I kind of reverted back to my motorcycle days habit on start up!
BTW nice few days of riding at Jonathan Dickinson State Park, Hobe Sound, Fl. Lovely weather. Paved roads, some hard packed sand/ gravel. Picture is Mr. and Mrs. Pace 500 taking a break at the SW fork of Loxahatchee River.
