KX500 running KX450f Wheels

Yep. it's been done for a while.
But, I was talking to Robert Reed (Umberto) and he asked me if the KX500 rear wheel bearings would fit in 450F rear hub.
My first thought was no... it's 25 vs 20mm axle size... but then I thought, hmmm. better check this out.

So I measured the hub ID on both hubs and.... They are the same ID!!!
Which means we should be able to press KX500 bearings into the KX450f hub.
You will need to use your bearing spacer from the 500 on the 450 hub but that's no biggie..
Here is the 450f bearing interchange info..

If bikes are for kids I'll never grow up.
