So basically i'd be living in a down town area and using it primarily to scoot to/from work and wherever else. i'm keeping my car for bad weather days and winter though, as we do get a ton of rain here in Seattle.
I will however need to (if possible) take it on the freeway for a short few miles of my commute. The speed limit is 60mph, though honestly rush hour is bumper to bumper, but still, somedays it'll be clear sailing.
i should also note i weigh 280lbs. ro hitting top speed on the scooter might not be realistic lol.

There are also some steep city hills here; think like san fran type.
So basically i'm trying to decide between the 150 international (or psycho) or 170i.
I also probably will wind up wanting to heavily mod it for more power and top end too. i noticed there seems to be WAY more performance parts for the 150. are any interchangeable with the 170i? (susspention and brakes, big bore kits, cams, stroke cranks, etc)
also, i'm trying to steer away from the Blur as i'm not a fan of the modern look. but i also don't want to kill myself on the freeway lol.
What do you guys think?
i should also add i don't have much scootering/motorcycle experiance, but i did spend the weekend riding the crap out of my friends 150cc MotoBravo in Seaside OR, and had it up to 65 indicated (probably closer to 50+ real) and felt fairly comfortable and cabable, though any faster and i'd be a bit scared lol. (i've ridden quads and atv's my whole life and am into sports cars so speed isn't a huge deal but on a scooter omg lol)
thanks.
