CRJperformance.com... has good stuff. I have the +1.5" extensions on my 350 plus the front/adjustable rear lowering kitREAL nice... handles like a dream. Rappy + CRJ stuff would be my way to go.

 

Go with the z400 if handling is important.

It's much cheaper to make the z400 smoke a Raptor660 in a drag than it is to make a 660 handle like a z400 on the trails or track.

Getting into spacers and such alters chassis dynamics too much, and unless you are going to add about $3000 in suspension parts you are not going to make the handling all that much better.

And don't believe anyone who says the z400 is not reliable compared to the 660r. There is way more documentation in favor of the contrary.

 

hahahaha the 400 guy sometimes 400 guys make me laugh. like i said once before a lowerin kit and wheel spacers. i own both quads the z400 is an awsome bike. but somebody said u canmake a z400 beat a raptor cheaper then you can make a raptor handle. can you build a z to beat a raptor with $250.00 i dont think so but for $250.00 you can make a raptor OUT HANDLE a z400

 

thanks for all the reply, how?

 

I have had an expirience with a kfx 400 and it wasnt very reliable, we dont know what caused this to happen and we have looked into it but somehow the timing got super screwed up and the valve got stuck in the piston. Also i had a head on collision with one goin about 10 mph and his frame bent 2 inches. Should that happen, I think not. all i got was a little dent in my PLASTIC bumper.
