Q. Is 14 bhp power is enough while other rivals have more than enough power for lesser price, say example 200s with more than 17 bhp. - 2019 Gixxer SF?

It all matter how you ride. More power doesnot mean more speed. Take into aerodynamics, posture, bike weight, rider weight n all. In college days, we raced 135 with 220... Pulsars..

If you choose 155 it will give less numbers over 200s

If you want more power then buy a gixxer sf 250.this can beat r15v4 ktm rc 200 and rs 200 ,duke 200 and ns 200
