u will be amazed dude, its not a typical suzuki ...... i bought it few months ago, done 10K on it ..... tested it to 165km/h for 5 to 7 minutes on motorway (ISB-LHR) ..... u wont get the feeling of losing traction ...... upto 16km/liter on highways and 12 to 13km/liter in city with a/c.....
I am against CNG so dunno about its performance on gas.
and yea one thing more ..... real pleasure is 3rd gear ...... I mean it buddy. Shift to 3rd gear when ur speedometer shows 60 and then floor the pedal ...... 3rd gear will take u upto 130km/h easily and u will feel the boost.
Last but not the least ...... Always drive carefully
