Thanks for the suggestion,will seek which one is cheaper and faster.
Mostly I needed its speed and reliability and also which don't drains petrol too much.currently I have Honda CD 70 it has point system engine(Non-CDI).its sometimes runs faster than honda CG125 and sometimes not.even though defeated many times against 125,70 bikes but point system bike sometimes looks ugly(but ugly bikes protects from thieves bad eyes).
