thanks for all the replies guys...i will hopefully be getting one soon and i'll let you all know how it goes.

 

i luv my z......im 6'4'', 220 and it is quite comfy for me..roomier than the 450's thats for sure...handles awesome.....jumps great...revs like nuts and wheelie at the drop of a dime anytime any speed....the reverse is the sh*t....with a couple small mods(kn, no lid, re-jet, slip on, +1 rear spocket) it becomes even more fun...runs like a raped ape...
smokes my twin peaks 700 no problem...and has had its fun with a stock raptor in a 300 ft drag a couple time...not to mention it'll out handle a rap any day...ive had mine (an 03) since new and have never had a problem of any sort..its never left me stranded and has taken everything ive been able dish out and it keeps coming back for more.
as a matter of fact im selling it to buy a new one....with even better shocks a little less weight and those hotter factory cams..a few mods and it'll be even greater!!!

 

i jumped mine many times and no frame problems yet
