When performing the protection detail on my R1150GS Adventure (write-up here), I removed the balancing weights from both wheels so I could apply the paint sealant underneath them.
Balancing the front wheel on the static balancer isn't a problem, but as most of us probably know, the rear wheel has an awkward hub that won't fit on a static balancer without an adapter. I assumed these adapters would be readily available, but when I searched online, I found that the available adapters were over-complicated and ridiculously expensive. I decided to see if I could come up with a simple solution.
One side of the rear wheel has a smaller hole where the plastic cap fits, I can't remember the exact size, but it's about 20mm and will fit on the cone of a static balancer:
The problem is the other side of the wheel, where the wheel bolts to the final drive:
This hole is much too large to fit on the cones of a normal static balancer. I took a callipers and measured it. The hole is slightly tapered. At the very outer edge, it's just under 42mm. When I measured as far in a the callipers would reach, it was just over 40mm. I decided that something with an external diameter of 41mm should fit just right. The diameter of the spindle of my static balancer is 12mm - I think that's fairly standard. So I decided I was looking for something with an external diameter of 41mm and an internal diameter of 12mm. After rooting around in my workshop for a while, I couldn't find anything that would do.
After thinking about it for a while, it occurred to me that a bearing would be perfect for the job, but I figured a bearing with an external diameter of 41mm wouldn't exist. I did a Google search anyway for a 41mm/12mm bearing and, low and behold, there is such a thing! It's a spare part for a Trend wood router. It's listed as "Trend B41 bearing". I bought mine from http://www.tools247.co.uk/ through Amazon for £11.16 + £7.49 P&P to Ireland. It arrived two or three days later and it's a perfect fit:
It was a tight fit going on over the spindle (as a bearing should be), so I lightly filed the inside of the bearing, to make it a little easier to slide on and off. I then put a cone on the spindle outside it to hold it in place:
The wheel doesn't rotate on the bearing because the other side of the wheel is sitting on the cone, so the wheel and spindle just rotate on the bearings of the balancer, as normal.
I just thought I'd share that because it's a simple, cheap solution and will hopefully be useful to others.
