the only diff between the ex and z400, is a diff engine, the chassis are basically the same, all suzuki did was stuff a DRZ400 motor into the chassis. if money wasnt a concern, and you like working on a bike, try finding a 250r, and modify it, once you do this, with the right mods, the 2-stroker will smoke the z and ex.

 

I HAVE A Z AND A 250 QUADRACER. THE EX WOULD OUT HANDLE THEM I BELIEVE BUT YOU WOULD HAVE SOME PRETTY GOOD MOTOR MODS. FOR ME I LIKE THE QUADRACER HANDLES AND SLIDES. MY Z IS A SWEET MACHINE. THE Z IS MY FUN JUST RIDING QUAD. MY RACER IS SOMETHING SPECIAL. I BOUGHT IT OFF A GUY THAT HAD IT FOR YEARS IN STORAGE. I STILL TORE IT ALL APART AND IT IS GOT SOME SERIOUS MODS DONE TO IT. I HAVE IT APART NOW DOING MORE. THE LAST TIME I RODE IT I WAS VERY PLEASED. IT IS WICKED FAST. MY Z IS STOCK SO THATS EXPECTED. IF I WERE YOU I WOULD GO WITH A 2 STROKE TO RACE. THEY ARE NOT TO EXPENSIVE TO MOD AS A 4 STROKE. EVERYBODY IS DIFFERENT SO JUST GET WHAT YOU LIKE THE BEST. I DONT CARE WHAT MODS YOU HAVE HAVE. IN SOME CONDITIONS A BETTER RIDER CAN BEAT YOU ON A STOCK BLASTER.
