Completely wrong on so many levels
..,and what levels may they be ?
.., so apart from Jakarta toll roads, AFAIK there is no restriction on bikes using them, especially in Bali .
As for the rest of my bike comment and your opinion they are wrong on 'so many levels' - to me that sounds like just your opinion , as I have mine , please explain ?
.., Before living in Indonesia full time, I did rent scooters for months and months at a time for well over a 10 years period with the latter part finally settling on the Yamaha Jupiters over the auto scooters , ie; until I finally made the full time move here and then I purchased a Yamaha Scorpio 225cc ..., That was 10 years ago now that Ive been riding that 225cc Scorpio full time ever since.
Not once ever - have I ever felt, nor been disadvantaged due it its larger size over a scooter, but I have been 'advantaged millions of times over and over by the added power. I can guarantee It will go anywhere a scooter can 'and more' , plus do it more safety and with more control due to its taller seating position and better handling and stability.
Also faster YES .., but not from sheer speed (although it much faster than a scooter) , but faster as in your overall journey and comfort from doing that quick overtake , and spotting and getting through the gaps with a quick throttle twist being the difference where a scooter just cannot compete - that leaves all the scooters still stuck in the pack and struggling not to rub handlebars with each other .
I still stand by my original comment 100% even without bringing up those hills and mountainous roads or the extra load carrying capacity (whether it be surfboards, Travel bags, Givi Boxes, panniers , groceries or rear passengers)
