Good afternoon, gentlemen. I was hoping someone might recognize this wheel/hub combination and could help with identifying it. I picked up some wheels thinking they were Bug Trophy wheels but when I tried mounting the Bug wheel hubs I already have, the holes didn’t match up. The center hole on the wheel is slight larger in diameter and the mounting holes are spaced slightly more apart.
If I can identify the type of wheel, I can then decide if I can complete that set more easily or continue to look for the Trophy wheels I originally sought. Thank you in advance for any help you can provide and thanks for all the help thus far!
Those look like and measure the same as early Yamaha RC100 front wheels. Pre 1980.
If that is a metric ID on bearing, then most likely those are Yamaha wheels.

I added some photos of some 1979 or earlier Yamaha rc100 wheel half and a front hub. Looks like what you have. I have seen 2 inch and 3 inch rim halves.

Thank you, Romero! There is no question about it, you definitely identified them for me, they are exactly the same as the one you posted photos of. I really appreciate it.
Terry, you are also correct about the bearing. I forgot to post that the Allen head bolt was 6 mm and the nut, if I remember correctly, was 12 mm or 10mm.
The bad news is I thought it was hard to find Trophy wheels, now I’ve gone and stumbled upon semmingly even harder to find Yamaha wheels. Im wondering, wasn’t the RC100 the only kart Yamaha made? Also, might you know if these wheels were used on any other karts? Thanks a bunch for all the help and information.
Those wheels are not that hard to find. Just nobody wants them. I still have a few around...somewhere. They came in real handy during the early 80's when local dirt racing became the hot thing. Not to mention it actually paid real money. Enough to cover the cost of racing and paying for beer and a meal at the local Spires restaurant on the way home from track.
