i've ridden CD70,CG125 and Deluxe.
and from the 3 of these, to me, deluxe is the king.
and btw a bike is about beauty also. You need performance on the track only. Every wondered why ppl still love to keep classic cars which have almost double the fuel consumption wrt to todays cars?
its about the aesthetic touches in the machines. if you are talking about performance, Deluxe delivers that too,
sure, Deluxe might have a little lower pick in the start, but on long-runs, it still beats the regular 125.
then again, i am not like you, i find things attractive in different senses. to me, i'd go for the looks of a bike first, and think about its performance later on. caz i dont race, i ride and enjoy.
