To give yourself more stability when coming to a stop, you might want to try sitting on the seat of your Ninja with one thigh,
that would allow better reach for the opposite thigh to the ground and stop as a tripod instead of tippy-toe to try to have both feet on the ground at a stop.
That's the way I stand over my KTM Rallye bike with over 38" of seat height, which is a giant mt. bike really:
I had a Ventana Marble Peak back in the late 90's, it was a solid bike lightweight for what it was equipped.
My current human-powered mt. bikes are mostly over 10 y-o now.. not many Balfa bikes were made, let along still ridden.
Even figured out a way to carry my bicycle on my motorized 2-wheel, along with bicycle helmet/shoes/change of clothes & tools/drinks/food.
