front axle for mag wheels are they the same on all

are all the front wheel axles the same for all mag wheels i am in need of one soon to finish my project. thanks if any one finds one on ebay for cheap let me know i ve already looked but didnt know which ones would work. thanks

Nope, and it depends on year/models.

Tell us the year and model of the front forks (77 KZ1000 80 KZ650, etc), and we can probably tell you what fits.

The forks that are on my bike are off a kz 650 b 4 cylinder 1978. The wheel i am not sure what it is off of. I was planning on using the 650's old front axle it was a spoked rim. I also think the mag front wheek i have may be off a early 80's 550 maybe?

I just took two 650 front mag wheels to the scrapyard

78 KZ650/750 twin/1000 all have the same diameter front axle, 80's KZ550 probably has a smaller axle.

Use a dial/digital/vernier caliper to measure the ID of the forks (where the axle goes) and the ID of the wheel bearings in the wheel, if they are the same size, then it's simply a matter of spacers (and maybe moving the caliper or rotor to line them up).

do you think maybe just changing out the bearings ones that have a larger ID and a smaller OD. thanks for the help!
