Gearing is 15/47 and it runs 115mph on the street or 108-110 on the dirt depending on traction

I'm game, does anyone have a 30 tooth rear sproket. If my bike does 105 on the dyno with stock gears than 125 to 135 should be no problem. Hell it revs out 5th in the sand.

130mph or so would'nt be a big problem. I'm sure I did 110 to 115 mph with 15/43 gearing on the beach and could pull much taller gearings.
