The pickup for the speedo is in the tranny output shaft. Most bikes read off the front wheel and sprocket changes do not change the speedo reading. The CBR speedo "reads off the rear wheel" but not directly off the wheel itself. The output shaft of the trany which drives the front sprocket depends on the rear wheel for information realtive to vehicle motion.

Guess I oculd have been more specific in my description. It works a lot like the speedo in cars. Speedo reading is digital.
