Need help deciding on my next quad. I've have alot of experience on quads and used to race motocross. I am 5'9 and 165ibs. I have a totally modified quad racer which is pretty quick but just doesn’t cut it any more. I love 2-stroke power but need more reliability and much better suspension. I do alot off trail some times day long runs threw ruff and mud or anything else in the path lots off open full out speed for long distance too. I also race off road and want to get serious about it and maybe start some xc. I ride track once and a wile.

MY question is what would be the ultimate quad for my riding. I was thinking maybe a yfz with some serious skid plates and suspension revalve for softer ride with maybe a new seat, twist throttle , pipe rejeted and removed lid but id like ur opinions. I like a 2 stroke type powerband and can never satisfy my craving for more power. Other choices are maybe a pred , Raptor , z400 with a 450 kit . RELIABILITY is key and I'm on somewhat of a budget so the quads im looking at are not new slightly used so if the year matters tell me wich ones are best. Any help would be greatly appreciated.
