Q. Why is Access 125 best than Activa 5G?

Access 125 is better than Activa 5G because of larger engine (more power, more torque at lower RPM, better engine life under harsher conditions etc.), telescopic suspension at the front for better ride quality (less j**k on shoulders), larger front wheel for improved road control etc.

Because its more comfortable for tall people and and is better in terms of power and seating position than the 5g
