Technically speaking, stock ZX-14 bars are NOT clip-ons. Clip-ons clamp on to the fork tube below the top clamp whereas ZX-14 bars bolt on over the top of the top clamp. Clip-ons originated from a need to create a more aerodynamic posture so the rider did not slow the machine by acting as a wind brake. When they came into popular usage in racing, fairings were in their infancy and most racebikes had only small flyscreens. Clip-ons were virtually unheard of on streetbikes until the cafe racer boom of the late 50's and early 60's.
