If I had a teenager, they'd get a 250. Anything bigger, they could buy it themselves. At that age, I'd want novelty of just having a motorcycle period to wear off before they did something stupid got themselves killed.
@Nitrox034232x: To a lot of folks here, they have this 250 on purpose, and have owned "bigger bikes" already. Referring to a change in displacement alone as "upgrading" can come across as a little condescending. Most of the people that have replied are seasoned riders who know what they're talking about.
C'mon, sko sko sko!
