1.its a 2-stroke
2.you can get a used one cheap! real cheap, like $1,000-$1,500 in good shape
3.something breaks on it, its a single cylinder air cooled 2-stroke, cheap to fix!
4.small and light (good for a woman)
5.upgrades are readily available for them
6.its a cheap/reliable/small/2-stroke
my $0.02
its what i will be getting for my G/F when $ allows
i think the only downside is the "putting around on it" factor
