these bikes are more different than the 300's than we actually think
I received my 300 brake rotor today. I just went out and ripped my front wheel off along with the rotor. Won't fit! The mounting bolts are smaller on the 300. The 250 hub has larger radius holes for the bolts to thread into. I ran into this when ordering the generic 300 rotor off ebay a few months back but thought the oem 300 rotor would just bolt right up. Well I called a few machine shops asking them if they could quite possibly copy the oem rotor dimensions and enlarge the 300's. They asked if the rotor was hardened, I dunno. At $65-$85 an hour it would be expensive. Why would Kawasaki do this? Wouldn't it just be cheaper to offer the same hub/rotor/caliper as the KDX 200/220 and KLX300/250R? These bikes may resemble the 300, but there are more things that are different when you get down to individual componentry than one may think. I also think the forks are somewhat different internally and the 300's rear wheel is a lot wider as well. Lesson learned I guess. I may swing over to the $65/hour shop I called and see what they say. Basically all they'd have to do is copy the oem rotor holes' dimensions and plug them into the lathe/drill, whatever they use.

Are you sure the front KLX250S rotor is not already floating? It looks to me like it is, i.e., it is not bolted rigedly to the hub. Well, the inner piece is, but the outer piece is connected to the inner piece by those ring buttons which allow some side to side movement, which is what a floating rotor is.
The back rotor looks like it is one solid piece, non-floating, but the front looks to be floating already.
FWIW, both rotors on the KTM 450 EXC are of the non-floating variety, they are both bolted rigidly to the hub.

the ONLY reason i bought the 300 rotor was i like the way it looks over the oem rotor. yes, it is semi-floating but the 300 one looks more rugged and racey. now i'm starting to wonder if i'm trying to make this bike into something i should've bought in the first place- a true MX bike. but then i think about just riding it anywhere where a MX bike would sit in my garage until i trailered it somewhere to ride it. then that takes me back to selling it and buying a new Husky. i need a therapist.

Nobrakes: Semi & full float look similar & both use a two piece design with a carrier & a rotor.A semi float basically allows no side to side movement (go press hard on it--its imperceivable at best) but does allow it to expand radially outward, ie when it heats up under hard braking. A full float allows both radial & side to side (axial) movement. If its full float there will be no question as with no force at all the disc should slide back & forth on the buttons. Manufacturer's even will say their rotors are full floating when in reality they are not.

yeah, i do admit i don't get enough riding time. it's hard when you've got 3 kids, a wife, and are going to school to boot. i just love to change things on my vehicles and bikes; you might say i'm addicted to being addicted to something. like a meth addict, i'm always chasing that better high but it just never quite turns out to be what i'm looking for. maybe if i change drugs and switch to displacement i'll get hooked on that. fwiw, the ebay seller i bought the rotor off of said he'd be glad to take the rotor back and issue me a full refund, that's pretty nice i think.
