x7 sprocket on x18

[x18]

well i want to change my gearing and i found a really cheap x7 rear sprocket will it fit my x18 the x7 sprocket has 6 holes and i think the x18 has 6 holes does anyone that has an x7 want to measure the size from hole to hole like from the top hole to the bottom (the bolt holes) on the rear sprocket

pbu has them as different....x7 has its own and the other bikes will interchange

[x18]

measure how large your x7 rear sprocket is and see if the teeth are even different if it aint lower in the number it aint worth switching out.
or if you can use a x12s rear sprocket, its what im useing and some x12s came with a 32 rear sprocket.

[x18]

well i dont have a x7 sprocket thats why im asking and yes the x7 sprocket is 33 teeth

[X7rocks]

if anything the hub size should be same as the x7 and 18.
the main difference i see is just overall size of the rim.

[x18]

thats mostly what i need to know thanks x7 but if someone can measure it to confirm this

[x18]

oh pocketbikeparts.com has the measurements for the x7 sprocket rolleye0010

[x18]

well i cant measure my x18s sprocket without taking it off does anyone have a x18 or similar bike sprocket laying around that they can measure the center hole of, the number of teeth dont matter

have you done a google search on the x18 sprocket

[x18]

well i found out the center hole is 1/8 of an inch smaller on the x7 and theres a lip on the x18 wheel to center the sprocket so basically it wont work i want a 33 or 32 tooth sprocket if anyone has one for sale pm me i really want a 28 but i dont know if my bike will pull that gearing

[X7rocks]

if anything just look up x12 rear sprockets there a direct bolt on.
i dont know if you can see it.but its a try.

Pic 1 is a pic of a X-19 bone stock with basic upgrades,-17/28 gearing and the bike pulled real good through all the gears and went from 38-40 to 58-60 after installing plug/plug wire/ 1/4" fuelline and fuelfilter /racing cdi box/28 tooth rear sprocket/hp pod style airfilter/ported and smoothed the carb and intake for better flow.....

The second pic is the rear wheel of my X-15 with 114cc monster kit.It had 14/22 gearing...when I upgraded engine to an electric start 125cc engine I punched the engine to a 140 and put the gearing to 15/22.Bikes hitting close 90 with my set-up and combo now.........

These engines were designed for 13/14/15 tire diameters.Check out the atc110 tire dia size and the ct110....

If you calculate the final drive ratio and not just the gear ratio youll see in the final drive numbers are still high...thats why on the atc110 and ct110 they come with hi/low sub transmissions to help give the bikes gear ratio more flexability.........
