Love it  

I used to ride dirtbikes and motorcycles with a guy that road raced a TZ250.  I used to ride a 1000cc sportbike.  Nevermind the skill advantage, his bike would run circles around mine on track days.  Light, powerful and very flickable.
Heck, I even got dusted by a Honda RS125.  I let the guy around me on a straightaway, only to have him disappear three quick sequential turns later.  He threw it around like a bicycle.
