i committed adultry guys....... i broke 1 of the ten commandments, i rode....... a YFZ450 05, ........ all it has is a retarded exhaust mod... and the rest is pretty much stock.... I FELL IN LOVE... its not my 250R but its damn near everything i would want out of a quad... i jumped it and it flew like a bike.... i raced around a track in my grandmas backyard.... and i loved it.... it runs like a two stroke... it almost has a "hit" in the powerband like a pinger.... i dont know i might be seeing one in my future...... i can get the yellow and balck for 4300 out the door with my work package... so at end of the summer i might be gettin me a 450 for the dunes... anyone got any input on how they ride in the dunes... i rode one before but not like a test run like i did on this one... i have no bad things about them anymore.... the one i rode was a 04 and i only made a few runs wiht it and was unimpressed but this one when you get some time to actually lean on it and run it man it was like it was on a rails... all input about the 450's are much needed, iam really looking into purchasing one
