I'm hoping the Grom will be good for an 8 mile commute on twisty back roads. I currently commute on a Yamaha Vino scooter. I'm hoping the Grom will go a little faster up hills and handle the bumps a bit better.
I don't know how big the engine is in your vino, but if you have the 49cc version then the Grom should have almost triple the power and torque so would definitely handle the trip better. The manual transmission and clutch should boost power delivery and efficiency in either case.
