So I'm looking at playing a chopper and I have no clue what some of these terms mean or refer to. I'm hoping you can all shed some light on them for me.

Strengths (choose 1 or 2): fast, rugged, aggressive, tight, huge, responsive.
What does being aggressive or tight do as a strength?

Looks (choose 1 or 2): sleek, vintage, massively chopped, roaring, fat-ass, muscular, fashy, luxe.
Is roaring even a look? I could see that being a weakness (they can hear you coming from 3 miles away).

Weakness (choose 1): slow, sloppy, guzzler, skinny, bucking, lazy, unreliable.
What does it mean to be sloppy, skinny, bucking, or lazy?

How do any of these things matter, other than in descriptive terms? Choosing to have a fast bike doesn't actually help its speed at all (taking the +1 speed battle bonus does that). I can see some of the weaknesses coming up, such as guzzler or unreliable (because running out of gas and not starting when you need to go are two bad things). What about the rest of it? I'm most interested in knowing what all the weaknesses are and what (if anything) the strengths actually do.

Thank in advance!
