Many thought that this one is the Honda Bros (sold in Brazil), but it is not so completely. Superficially, the Impulse?s 149.2-cc engine displaces the same as the Bros. However, Hero have modified the cylinder head slightly and reduced the compression ratio from 9.5:1 to 9.1:1.
Hero have made sure that their forte ? fuel efficiency ? remains intact while not forgetting the fact that the Indian customer needs more power and torque in the lower revs.
