At the heart of things is the familiar 97cc single cylinder air-cooled engine, which drives the entire commuter range of Hero motorcycles with the same displacement. This engine has been worked upon to deliver a little more power and torque compared to before: the current figures stand at 8.3bhp and 8Nm of torque. The ever-present four-speed gearbox with an all-up pattern does transmission duties. The Passion Pro gets telescopic suspension in the front and five-step adjustable dual shocks in the rear with attractive scarlet springs. The Passion Pro also has the option of 18-inch cast alloy wheels instead of the spoked rims. Choose the alloy wheels, and you can opt for a disc brake as well. Both the drum and disc variants of the alloy wheels have an electric starter as standard, but you can opt for it on the spoked rim variants. The instrument cluster integrates a digital display to show the fuel gauge, service reminder, odometer and the trip meter. The speedometer remains a legible analogue unit.
