i have to make a decsicion on which fourwheeler i want to buy and I need some help so here are my choices 450quadracer,450kfx,450yfz and know wat i need to know is which on is the fastest,powerfulest and the best bang for my buck?

 

What do you want to do with it? MX, XC, play riding, trail riding, etc? Stock, out of those 3, the 'Zuke is probably setup best for MX, the KFX best for XC. YFZ probably has the biggest aftermarket, being that it has been out longer. YFZ might be a better 'play bike' as it is small and feels flickable to a lot of riders.

When buying something like a 450, I think looking at the strengths of each particular model and deciding if those strengths figure in with your intended use, as well as trying them out/sitting on them to get a feel for ergonomics is a much better way to pick one then just going with which is faster, more powerful, etc.

I am not sure on their prices, and only you can say how much your local dealers are willing to deal and drop prices, so I can't really comment on the bang for buck...
