I took apart my 1958 Cardellino rear wheel today to clean the bearings and replace a worn tire, I was very surprised to find the wheel hub is just like an old school bicycle ( to be fair the Cardellino is pretty much a bicycle with a small motor, skinny 20" tires et all).

The axle is located into the center of the alloy hub with cups pressed into the hub, 10 loose ball bearings per side and cones that pas through the axle, the axle has centering nuts to keep the cones tight to the ball bearings just like a bicycle.
I guess it does the job well enough given the light weight of the machine and the relative slow speed it was designed for but I sure was not expecting that.
Anyone ever seen this set up on any other motorcycles?
