Advantages
Easy to maneuver
A wet weight of 101.6 kg makes the Grom easier to push around and handle at walking speed.
Low fuel use
Its 1.41 L/100 km fuel consumption and estimated 433 km range can mean fewer fuel stops.
Optional ABS
ABS is available for riders who want braking assistance to help reduce wheel lockup.
Things to consider
Limited power
With 10 hp, acceleration is modest, especially when trying to pick up speed quickly.
Chain maintenance
The chain final drive needs periodic cleaning, lubrication, and adjustment.
