Bhai jaan Deluxe has Less Acceleration and Speed than Honda CG125 Classic.
Deluxe has a wonderful shape and aerodynamic design and is heavier than CG125 Classic
Classic has the wonderful sound ( But you can attach Classic's Silencer to Deluxe )
Deluxe also has better road grip and it has wider Tyres.
Local mechanics know less about Deluxe and more about Classic.
And many more things which i may not know but i say Classic is Best! It has better Petrol Average and has better acceleration and speed than Deluxe.
