There's been a lot of questions lately on what aerox (or mbk nitro) parts fit what other Yamaha bikes. To properly answer this question we are gonna need some scoot'r guys across the world to join forces and share info. This is what I got so far...
-98 yq50 forks seem to fit older zuma(prebug) and jog frames, as well as clone bikes and Chinese bikes like tng and keeway. some pre-03 mbk nitro forks seem to fit older zumas and jogs
99-02 & 03-12 yq50 forks seem to fit later zumas(bugeye) and some bigger euro jogs. These are the fork stems with the "step" in it.
Aerox yq50 seems to be 190mm disc front, 180mm disc rear.
Aerox 100, zuma bugeye, and bws 100 look like there 180mm from and 130mm drum rear
Zuma prebug, older jog, some clones are 110mm drum front & rear
Aerox's have rear disc brake caliper mounts built into the frame
Aerox yq50, later jogs, and all zumas are longcase motors, with some differences in the final drive.
Older jogs and clones are mostly shortcase, even the "longcase" clone motors with "12-"13 wheels. Most also seem to have similar final drive dimensions.
If any body has any pertinent info or wants to edit this info, please go ahead.
Aerox's have "13 wheels. Some 100cc aerox and bws 100 have a 130mm rear drum brake and the axle spline count is the same (18) as a bugeye zuma. These wheels are rare, but bolt up to u.s. bugeye zuma cases.
Zumas(bugeye & prebug) have "10×3.5 wheels
Zuma bugeye and clones seem to have 18 spline axles, early jogs and zuma prebug seem to have 16 spline axles
Aerox wheels use a smaller rear axle that doesn't fit the u.s. zuma cases.
Any body in an area where aerox's are common? We need you! Your info is valuable!
Aerox 100cc has 190mm front disk and 50cc are the same size back and front as far as my digi calipers say lol anything with a 4vp 100cc motor all internals can be swaped but bws oil pump is electric and crank doesnt have hole for pin to run auto oil as aerox 100cc as far as i know go pre mix, every part from a 50cc aerox will fit 100cc except internals of motor and box most of my after market parts for aerox 100cc are listed as bws 100cc ive had no problem swaping 50cc part for 100cc parts im only sure with bws and aerox 100cc parts and aerox 50cc parts anything i need for 100cc i get off 50cc AEROX swaping for Zuma parts are a bit more tricky i have 3 AEROX 50cc and a 100cc aerox if you look up parts and look at ehat eles they fit somethimes u will find it will fit they just want you to buy by brand name dont know if this helps at all

For 100cc version wheels are direct swap. The only difference is disk size. Bws has 180mm disk and aerox has 190 also bolt pattern isnt same. But kymco agility 125 disk has same bolt pattern with aerox wheels also 180mm outter diammeter. So if you find a 100 cc wheels rear ones goes directly in front ones must change the disk.
I’ve been running Aerox wheels and a CPI GTR adapter which bolts up to the us Zuma axle. Comparing the CPI hub to an Aerox besides the spline being a different size the recess for the disc to bolt up is different. An Aerox disc will fit on the CPI but a CPI disc will not fit an Aerox. My gtr disc measures a whopping 210mm, 8.25”. OD of the 2 hubs are the same, the Aerox is 42mm thick and the CPI is 44mm.
My cpi gtr hub came with a 190mm rotor on it- and I'm using it. It barely fits, and I needed to clearance the caliper a bit to make sure it didn't hit the wheel.
On the front, I used a Chinese 180mm rotor to replace the 190mm mbk nitro rotor, so I could use the u.s. Zuma fork. The U.S. Zuma fork is designed for a 180mm rotor. I'm running an Aerox caliper in the front with spacers to line it up with the Chinese flat 180 mm rotor. The oem u.s. zuma front rotor is dished.

Maybe this spot suits this image well... While I had my Aerox forks apart I snapped a picture just to illustrate how things go together. Some parts are still in the legs but these are the easiest parts to pull apart.
