400ex does 60 tops.
mine is basically stock and tops out at 70 mph
It depends on what model. But the 2004 400ex can go as fast as 70-75mph.
it doesn't go, because it's a honda.
54 to 58mph (in stock)
87 mph
70 to 80mph.
it will run 72 mph
my 06 topped out at about 50
My 400ex is stock and it will run about 87 mph. there is no way they may go 65 but no way 87 your crazy
45 mph max
Depends how much money you want to invest into it.
i say 80 to 85
