Clearly, ZX14 front wheel == ZG14 front wheel...the part numbers are the same. Whole front end looks the same.
What about the rears? Obvious difference is the shaft drive insert vs. chain drive insert. They are inserts, so not critically different. Out with one, in with the other.
UNLESS...the shaft drive insert is held in the hub by a snap ring...but not the chain drive...
Is that the ONLY important difference?
Who knows??
Inquiring minds and all that...
