scootley

I live in Asia, where Honda sells several scooters that are 100-125cc. Some of these scooters are fully automatic with CVT/V-Matic transmissions (no shifting, no discrete gears, no clutch). Some of them are semi-automatic with discrete gears, shifting, but no clutch.

For 2 such bikes that have an engine with identical displacement, torque rating, and power rating, but one fully automatic and one semi-automatic, which bike can accelerate faster?

Please back up your answer with a citation/reference if possible.

I know that acceleration is somewhat operator skill-dependent, but please assume the rider is a "good, experienced shifter".

Bonus question: And how does acceleration of automatic and semi-automatic compare with a traditional manual bike (shifting, discrete gears, clutch), with all other things (displacement, torque, power) equal?
