i think if we go on calculations then still delux can not reach to cg125/ dream........... because if stock cg sprocket is put on to the delux then still delux 18'' rim+ 90/90 wide tyre would lag in acceleration as compared to cg125/dream(its very little difference but still would lag little bit).... and 2nd low weight of cg125/dream will also support cg125/dream..... although you have minimize the differences but still cg/dream got the plus point for racing enthusiasts...... this is true that delux has less vibration and is good at corners....... but one thing thats push you to accelerate more more and more is actually the vibration of cg 125.......... and actually racing enthusiasts actually wants vibration feeling because they had never ride the bike for sake of comfortable ride........!
