With the current petrol prices, i'd choose economy. I can live with less acceleration because getting a CG-125 was just passion, not that i like speeding or showing off.
Besides, with tuned down mixture, you are still able to do 120kms ... so why even bother? The ONLY thing you'd lose is the quick acceleration. But it still accelerates like a 125cc should.
First of all, you HAVE to accept a bitter truth here. Before that, ever wondered why there are so much mechanics of HONDA (specifically for CG-125) ONLY?
I tell you. More than 25 years old technology engine Honda is still using with a couple of tweaks .. and there are those people who never had gone to school and from early days of their life, they are working at a shop of ustaad jeera or ustaad kareem to learn bike's engine mechanics and with a vision to be a 'ustaaad' themselves.
And then there are some new comers in market, who specifically like to brag about everything they do ... like پھڑیں marna.
Now the bitter truth ... You CANNOT just ignore a mechanic's comments when there is a 20+ years of experience speaking out of him. If you do, i say there is no idiot bigger than you in this world, because you are arguing with a man with most experience, from the times when you weren't even born in this world.
WHat? Amused You?
The thing is that i dont trust mechanics, atleast not all of them. I choose my mechanic after extensive research about him, and about his experience or person life. The mechanic i have now ... have nearly 25 years of working experience.
Tuning a bike's mixture is not a rocket science. Even i know where the screw to set the mixture lies. But wo kehte hain na ... جس کا کام اُسی کو ساجھے
Doing it yourself and then get it done from a profession 'experienced' person ... makes A LOT of difference.
No No you misunderstood. By underpowered, i mean they have shorter gear ratios, and they apparently feel less powered as compared to a normal CG-125.
According to Honda (excuse me if i dont state the exact statement, but it was something like this) ... 5th Gear was not meant for speed. It was meant for smoothness in ride, and fuel economy.
About the engine, kindly read the specifications over wikipedia, and i 'hope' its the same engine use by Atleast previous manufacture by japan 
Ravi, Deluxe, CG-125 ... ALL are using a 124cc engine.
