My bike has FULL mods save for a BBK, and it does 65mph on the flats as per GPS. Lighter bikes (mine is a type-23 style) may go 1 to5 mph faster with mods, but no stock gy6 can even touch me.

One of my club members swears his type-04 (handsome boy) 50cc with BBK and full mods does 70 mph (like SWEARS!) and even our old beater type-04 150cc smokes his bike.

Most mods WILL NOT increase your top speed, they just increase acceleration to THE SAME top speed it had stock.

A stock 150cc gy6 w 13" wheels goes 50 to 55mph top speed. You can tune it out to about 60mph with careful mods.

As for what to do; read my sig, and do those mods, you'll get the same results. Don't listen to people about bigger carbs, as bigger than 24mm are simply over-carbed and aren't making more power, just running rich and wasting fuel. A gy6 157qmj likes 24mm w 105 to 115 main jet, any more is way too much.

Hi Tommy

Sorry I should clarify:

no 50cc 4t engine is that fast, 50cc 2t, well that's a whole different game. My 2002 Kymco Yup 50 2t has been gpsed at 51mph.

Also; Spectre is balls-out modded :P
