OK, I just wanted to see for myself. I was told years ago that the 1200 rear wheel is 5 ˝” and offset to the right, and the 1100 models were lined up correctly with their 5” wide wheel. I didn’t question that the face of wheel would be ˝” more to the right when aligned with the front wheel until I saw Chris’s (ZRX24) post stating it was 10 mm. I realized then that the tire could be anywhere relative to the hub.
Fine, I will check it out. I decided to level the bike, find the center of the frame, and drop something through a hole at that point to find the center of the tire over the axle centerline.
There are a lot of things that could go wrong when doing this.
1. Frame could be bent.
2. Hole might not be in the exact center.
3. Swing arm could be tweaked.
4. Might not mark the exact center of the tire.
While I do measure things for a living, it doesn’t mean I can’t make a mess of it. I tried hard to get a correct result, just the same.
I shimmed the wheel on the stand with a level across the frame. I made a cardboard strip to insert between the rails as it is hard to measure a round item. I measured and marked the center point on the strip. I marked the fender at the half way point and drilled a 1/8” hole. I inserted a new 1/8” rod and set it plumb with a level. I have a 300’ fiberglass tape and draped it across the tire from edge to edge and marked the center with chalk. After getting a result, I remembered I had a plumb bob and rigged it through the hole. You can see the line overlaying the mark on the cardboard strip.
While there are too many variables in this to call it science, I got about 5 mm with both methods. I don’t know where he got his info, but for me, this means that Chris is absolutely correct about the 10 mm offset at the right side.
I have been doing it wrong all this time and I pledge to change my evil ways.
