The YFZ is a freaking awsome fourwheeler...I'm 15 and just got the 07' YFZ 450 SE...but I was a big jump in speed and power wise from a Warrior 350....I rode threw trail just find and hit some nice jump I love the thing lol...even all my friends that are Honda riders say Yamaha sucks and they said they liked it.

 

have fun man...but ride smart,being 15 remember that bike can kill you after one mistake..
