> A modern 300cc four stroke Vespa will use 3.3 litres of fuel per 100km
Uh, I know motorcycle engines aren't particularly fuel-efficient (it's not a priority), but there seems to be, er, room for improvement.
A 2026 Honda SH150 uses 2.2 l / 100 km (up to about 70 km/h) and is very quiet. Made in Italy too.
you can get some 125cc motorcycle/scooter and run on half that
Scooters main priority have been cheap practicality. Fuel efficiency is part of the “cheap” part.
Yamaha’s blue core engine used in its mid sized 300cc scooters can do 2.8L per 100km. It’s 125 engines can do 1.8L per 100km.
They’re incredibly efficient little vehicles
So far electric scooters can only compete in inner city with the equivalent power of a small 125 and limited range/speed due to size/weight constraints
