Hero Impulse Specifications

Hero Impulse specifications is one of many posts, that detail out information about the Hero Impulse. I have put up the details as seen in the Owners Manual provided with the motorcycle. I did look at the Hero Moto Corp website, with an intention just link out to it, but its incomplete and erratic. More over, given that they may phase this motorcycle out, it makes more sense to have it here.

Hero Impulse Specifications Owners Manual

Isn’t it great that the manual also has an orange motorcycle on it. And, the woman at the showroom left no space for doubt about who owns this.
