The N1 Shift Drums have a 0-down all-up shifting pattern, and eliminates any
possibility of catching neutral on aggressive 1st to 2nd gear shifts. Neutral is
below 1st. The N1 drum is also popular with handshifting bikes where finding
neutral without doubt or error is critical to safety or riding/looking smooth.
