I've always wondered about this non-linear offset. After all, the speedo is mechanically linked to the front wheel, so shouldn't the offset be the same percentage all the way up? Then I realized that speedo needle is magnetically driven against wound-spring. So it's likely that the offset can be non-linear; the spring gets tighter and tighter as its wound-up, require more and more force for each incremental movement..
