dude the best in that class is still the activa.
People who ride the activa have high praise for its acceleration, handling and reliability.
These very people do not approve of the Dio as they complaint of an overall "metallic" sound.
For the aviator , they say its heavier and just doesnt come close to the activa on the riding comfort factor.
As a second option, they regard the HH pleasure as a very good alternative to the activa.
