I have been using swish 125 from last may 2013 and covered almost 15000 km .
Advantage:
Mileage: 45-48 kmpl.
Great pick up for quick overtaking.
No vibration up to 90 kmph( my max speed is 97kmph)
Disadvantage:
Headlight Beam.
Brakes(above 60kmph).plz apply front brake first and suddenly rare to avoid skidding.
