I finally found a flaw. For the longest time I have searched for one, but up until now my GTi300 has been a perfect scoot. However, I found a particular, but minor short coming; I can't just ride off the curb where I like to park in front of my local Albertsons grocery store. The underside is just too low and will hit the edge of the curb on the way out. I can easily go over this curb on both my Fly 150 and Scarabeo 150, but the GTi is just a little too low and made this awful scraping noise. I'm bummed...
I know this is dumb, but nothings perfect, right?
