Scooter engines are very mildly tuned and only have half the specific power output of a high performance sportbike motor. This means that your scooter can handle WOT for a long time although if you do it enough it may shorten your engines life some in the long run.
However, I personally don't feel comfortable running WOT for that long so I'd take the longer route.
Still trying to figure out what I wanna be when I grow up!
If I ever grow up!
