how fast does a stock z 400 go???

 

66 to 68 stock

 

prolly around 73 give or take 1 or 2 mph

 

dont think so

 

depends how much u weigh. i would say anywhere from 68-72mph

 

i was racin my friend when he was on his street bike and his speedometer said a little over 70 when we were side by side and i didnt kno if it was right cuz its old but thanx guys

 

My buddy Says his 03 Z400 will do 75MPH all Stock and he is Real big for 15 he is like 175LBS

 

sounds pretty close to me

 

iam 5 11 190 my 04 will do 69.

 

5'10" 170# and mine'd do 70-71 stock. That's riding past to a prairie 650 w/speedo doing 69. I'd believe 75 if he's going down a hill. But on level road they're hard pressed to do 70. you gotta scoot you a$$ way back and lay on the tank to get that last mph above 70.
