Hey RexIQ
That is Under stand-able, It would be best done on a freeway on ramp at a light. Start in "S" mode and move shifter into "D" Mode at about 40mph without taking your foot off of the gas pedal.
I have tried it this way but only at about 1/2 throttle.
A 65Mpg Vespa Scoot, what size scoot is it. Nice!!
I have a Suzuki, Burgman 650cc Scoot it has a CVT trans with Power & Normal, Like our IQ's, the "P" Power mode is significantly Faster than "N" Normal Mode.
I have raced Harley's with My scooter and it is no contest, I am sure they must be humiliated to be beat by a scooter. They dont know that it is a Fast Maxi-Scooter with a 650cc Twin cylinder engine & a real efficient CVT trans.
It gets 50 MPG, not bad for all the performance it has.
