genesis,
I'm 16 also. At 6'3 210 I'm a pretty big boy. I've rode vipers, srx's, rx-1's, and my vmax sx 600. wednesday i sat on every new model for 06 and I fell in love with the Vector GT. The black one is just SICK! the mono shock rear suspension is amazing and the adjustablility is insane as well. all the way hard was stiff as a board. all the way soft was to the point that i could bottom it out myself on the showroom floor.the Piggyback shocks AWSOME. need I say more? 120 ponies is a lot. If I could buy a sled this year, it would be the Vector GT in the black. I could rattle on for hours about that sled it's so awsome. I was not at all impressed with the Nitro, Attack, or Rage. If you're considering a 4-stroke, consider the RS VECTOR GT.
