ok heres the deal im going to get a new 4 wheeler im looking into honda 450r kfx 700 or the yamaha yfz 450 i used to have a 400 ex so im wanting a bike i can get the most power out of and since all prices used are about the same now adays all i have to do is get later years so again im needing help as to which will be the best for most power ,highest speeds and best reliability i can handle a atv with power as to my old 400 ex i would have piinned the whole time down a 3 mile dirt road with sharp turns that a car would have to hit around 20 to not slide

 

A DS650 is a really fast machine, I know that much. I don't know about mods or reliability but they are rockets.

 

If your looking for handlebar jerking power. i mean power that will just about throw you off the quad. Get a yfz450. Do the cam mod (look it up, I have one with it done) and get a GYTR exhaust. The are insane fast.
