I have this vehicle since over a year now. I must mention it's best in market. May it be looks, performance, power, comfort, handling, it aces all these fields.
Although I must mention it's a bit noisy. I personally feel that Activa is smoother then access 125 but considering all other factors, Access 125 would be the best deal.
About the fuel consumption, my access gives me mileage of around 40kmpl, on road admit a lot of traffic.
One personal suggestion, go for white. It doesn't fade away with time. Black looks good but it has to be maintained.
