I'm buying an F4i with a 70t rear, & I was just wondering what a stock rear was? & Does anyone know my aprox top speed?

 

46 is stock .... 70 is ridiculous

 

46t top speed is close to 170 70t maybe 90mph

 

about 90 on the rev limiter. if your ridin streets a 56 is mint but i like a 62-64 tooth myself and you can still ride streets.

 

+24 isn't too bad. Close to what eddie ran.

 

I'm decent with the faster stuff, I can do usually anywhere from a 1/4 mile to alittle over a mile. I have really good throttle controll, & great brake controll also. I was doing this on my F2 after 1 1/2 weeks and it was first rocket.
I'm buying the F4i & I want to start learning the slow stuff, Scraping 12's, Riding Idle, and eventually learn circles hopefully. I don't want something as big as a 70t cause I need a better top speed than 90mph. What size rear sprocket would be good for this with a decent top end?

 

eddie had a 72 - and it was retarded, way too much ...

 

Just put a 52 with stock front and I love it. Second feels just higher than stock first gear.

 

i have a 57 on my f4i and its good

 

70 will hit the ground when you turn left, 60 is about the biggest that wont

 

i have a 66 tooth ,never came close to the ground,and i lean that bitch to the limit....and an f4i wont do 170,more like 135

 

I had a 66 also and i got rid of it because it hit and slid out alot when i started working on fast circles. My 60 comes close but never touches. Do you have a 190 tire?

 

135 my ***

 

70 is too big
your sprocket has more teeth than a trailor park

 

because you ride a geared f4i and would know huh kid

 

if you had really good throttle and brake you would be well over a mile......

 

 

I believe morrow said a stock F4i would do 135. That's bullshit.

 

stock ok ... although TRUE top speed is probably only around 150

 

Agreed.
