I see I am a bit confusing the offset I am referring to is when spoking the rear wheel to ensure the rim sits in the middle of the bike the same as the front as whilst lacing the wheel you can move the rim from side to side with reference to the bike centre 
I don't know how much more I can say lol
As i have already advised several times.
The rim on these should be central to the hub to put it in the centerline of the bike.
I don't know what more i can say either as that is the anwser you needed.
I've said exactly the same thing at least 3 times....

Some sad information included here but reading  past that there is good information.

Interesting reading Mikaw.  I'm left with the question of what advantage is there to having offset wheels?

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

I wouldn't say there's any good information there at all, DO NOT offset your rear wheel, i've never read such garbage...  On a slow pile of nuts and bolts do what ever you like, but on anything, with any sort of power that you want to handle correctly, put BOTH WHEELS exactly at centre....  I know people do offset wheels to make them fit, that's the lazy way of fitting wider rims, make the sprocket carrier align, if that's not possible then use offset sprockets, offset wheels effect handling and tire wear. I would NEVER build anyone a bike with offset wheels..... Just as a side note, I've been round quite a few circuit race bikes over 40 years or more, they  used to string line the wheels, and now use lazers for alignment, there are piles of videos on you tube about wheel alignment on motorcycles. 
PS, I don't give a damn what Harley do.....

Intuitively I think the wheels should be in the same plane so that forces are balanced.  Braking at high speed with offset wheels would be a challenge.  I think the bike would try to rotate.

The ZRX1200 came from Kawasaki with the rear wheel offset to the right for chain clearance. Does not seem to be a problem.

750R1, I think your a little hard on the article. I understand in race trim offsetting the wheel centerlines is not recommended. I don’t think the article is suggesting offset is the correct way to go. It says that in some cases an offset counter sprocket can be used to put wheel centers inline, and keep drive components aligned. I get the over jest of the post is more about drive components (chain/sprockets) needing to be aligned. If it’s not possible to do that within the drive components itself then the proper way is to offset front and rear wheel centers while keeping the center lines parallel.

That doesn't make it right, there's a ton of conjecture over it and IMO, it should have never been done like that.  The 1100 didn't have an offset, when Kawasaki fitted bigger wheels to the 1200  they were lazy in setting it up, The guys that race the 1200's sort the offset problem out. There are also reports about handling anomalies with the 1200, Understeering to the left, and oversteering to the right.

Mikaw, I'm a bit of a pedant when it comes to handling, so when I see anything that goes against what is widely recognised and accepted as correct, I have my 2 cents worth. If anyone wants to set their bike up with a wheel offset, go for your lives, just don't try and convince anyone its correct....
