I wouldn't be surprised by this happening. I think the revs are rising to help the alternator charge the battery to replace the charge used by the lights/fan.
However as you say this doesn't happen on other similar micras I'd suggest you get the battery checked to see:
1. That it is holding charge properly
2. That it is the correct fitment for your car
A garage should do this for a beer.
While you're there ask if they can check the alternator too.
All the best - let us know the outcome
Cheers.
