best gearing for top speed?

Ive looked all over this site for the info but just couldn't find it =/


so yea like the title says what would be the best gearing for achieving top speed (over 60 MPH)

Thanks!

I was thinking front 18/17 and back 33?

its an x-18 by the way

(p.s i really don't care about acceleration just top speed)

THere is a HUGE STICKY answering your question. Look at the top of the page bucko.

Here i will copy and paste for you, i'd hate for you to be searching the forum for hours just to find it.....................................

3.17:1 - 12T front, 38T rear
2.71:1 - 14T front, 38T rear (stock setup on many X18s)
2.53:1 - 15T front, 38T rear
2.38:1 - 16T front, 38T rear
2.33:1 - 12T front, 28T rear
2.24:1 - 17T front, 38T rear
2.11:1 - 18T front, 38T rear
2.00:1 - 14T front, 28T rear
1.87:1 - 15T front, 28T rear
1.83:1 - 12T front, 22T rear
1.75:1 - 16T front, 28T rear
1.65:1 - 17T front, 28T rear
1.57:1 - 14T front, 22T rear
1.56:1 - 18T front, 28T rear
1.47:1 - 15T front, 22T rear
1.38:1 - 16T front, 22T rear
1.29:1 - 17T front, 22T rear
1.22:1 - 18T front, 22T rear

if you want a topend of 63 or w/e just get a 22 rear

imagine switching the front sprocket with the rear sprocket and then riding? 33t front and then 14 rear? holy smokes.

17/28 is good for 92-97mph ... if you have the motor to pull it

what would the stock motor do with that gearing?

fall on it's face

no, really. what would that gearing do would that give it crazy *** top end?? it sucks that you really cant transfer the front towards back because 1 the motor doesnt have space and 2 the sproket isnt set up that way but that would be crazy lol, so front gives you accel and back gives you top end?

finch explained it pretty well...

better.. then pretty well he said it all the 110 motor simply has no power to pull that gearing
it cant even pull the gearing for a 17 front 32

that was with my small motor best i got was 98mph

shooten for 110-115 this time

both gears effect acceleration and top end. the ratio of teeth on each sprocket determines this. (check the graph earlier posted)

oh, when he says the motor would fall on its face, he means it wouldnt pull through all the gears. i think you have the idea that a bike can pull through whatever gearing you throw at it, which isnt true at all.

yea i knew that i just didnt understand what he was trying to explain by stating that it would fall on its face. thanks for the clear up

i wish i can pull those numbers
