How do I know what gear My motorcycle is in?

While riding your bike at 4000rpm, check the speed of your bike. The first digit of the speed is your gear. For example: while riding a pulsar at 4000rpm, and you notice a speed of 45kmph. Then, the first digit of your speed (that is, 4) is the gear you are running in.
