I bought this scooter one year ago.when I bought it, it used to run very smoothly but as months passed it started degrading.it’s mileage was never more than 50 but they promise to have 60.they give free servicing for one year but in that servicing they do nothing much.just wash it and fix small problems.the scooter starts vibrating when it’s speed is increased above 60 km/hr.this scooter is not suitable for long run.my scooter is just one year old but if you will ride it you will feel it’s ten year’s old.
