What size axle

[s12silvia]

hey guys ive just bought myself a 2nd hand 125cc Atomik bike, i dont know stuff all about what model it is or anything all i know is that when i was riding it today i snapped the hub where the rear chain sprocket screws in. So im looking to buy a new rear wheel but i have no idea what size my axle is whether its 12mm or 15mm? Can anyone shed some light on this for me?

Cheers

Do you own a ruler?

 

[china boy788]

check the size of the axle nuts

12mm should be 15-17mm
15mm should be 17-19mm,

 

[mattbombers]

umm, check with some verniers? im guessing its 12mm anyways

 

[s12silvia]

well the thread sticking out the end appears to be 12mm but wasnt sure if it fattened in the middle or not. so that would mean that its a 12mm axle yeah?

 

[mattbombers]

best thing to do, slide the axel back the other way a bit so you can measure the axel itslef

will do that tomorrow, was just kinda hoping someone could tell me so i could order new wheel tonight. cheers for help guys. im sure you'll see much more dumb questions from me too come. Have never owned a bike in my life so yeah am an absolute noob

If it is an atomik motox (the kind with telescopic forks) it is 12mm rear and 12mm front. If it is an atomik nitrous (the kind with usd forks) it is 15mm front and 15mm rear.

 

[s12silvia]

i have no idea what either of those things are lol. not only is this my first bike but ive also never been around bikes

 

[mattbombers]

grab a piccy and we can set you straight

 

[s12silvia]

only picture i have at the moment. if cangt help ill just pull it apart tomorrow and measure it.
Cheers for help guys

 

[mattbombers]

yeah, my moneys on 12mm.

 

[atomik boy]

nice what sort is that?

 

[mattbombers]

Lol, he said he doesn't know what model it it

 

[atomik boy]

yeah but i thort one of you guys would know?

 

[china boy788]

im gonna say thats 15mm,

 

[sam93]

Thats the old atomik RS and is running the new style hubs and wheels which means its should be the 15mm axle. Hey Bud get out a ruler and pull the wheel off and measure the I.D (I.D stands for Inner diamiter) of the bearings...That will tell you what size you need. Then to buy a new one go to DHZ Mini Moto and purchase a new one

 

[s12silvia]

[s12silvia]
