In 2010 at Lake Gairdner, I ran a stock Suzuki RGV 250cc (2 stroke V twin) at 119mph, it was stock with no fairing.
It is a light bike 306lbs/139kg dry weight and I am glad I had suspension.
I eased it to full RPM in 1st then accelerated as hard as I could till it was topped out.
It had some small amount of wheelspin once up to speed, the rear tyre wore to flattish profile in the middle after several runs, but it tracked really straight.
