Off center , staggered-hole rim-patterns ... add lateral bracing.
These are less necessary to a motorcycle ..that can lean its tires into its turns .
But would be more necessary for sidecar work or 4 wheel car work
Where a wire wheel sees more lateral loading any time the vehicle turns at speed .
Without efficient lateral bracing a spoked wheel can "taco"
Staggered off center rim patterns were more common in the early days
Where simple radial bicycle spoke patterns were evolving to handle more speed .
Acceleration and braking torque ... and side loading
This early Rudge wheel (from a Rolls Royce ) seems overly complicated ... but probably reflects
The Material capabilities of its day
Notice the cross-lacing on the inside hub ... to handle rotational torque
And the more simple radial lacing on the ouside of the hub for sideway forces .
