KXF Wheels On a KX

[Kawafornication]

Hi just purchased a near new set on Talon Excel wheels to fit a 2006 to 2018 KXF with the intension of fitting to a KX 250 1990, I am guessing with some new bearings to suit smaller axel and custom spacers they will fit with the exception of the rear due to the larger rear disc found on the KXF, I think I would be right in saying the 1990 has a 220mm rear disc and the KXF has 240mm so need either an oversized calliper relocation bracket which I do not think is made?? or a smaller rear disc??

Does anybody know if any other discs have the same stud pattern as the KXF, may be a KX 85 front disc etc? Or may have to get a KXF fit disc machined down 10mm, thanks in advance

Just modify or make your own caliper adapter. It isn't as hard as you think.

450 to older 20mm kx125 kx250 kx500 rear wheel adapters



I have a drawing somewhere..

Thanks that looks like a plan, I do not weld so will pass that job on! are you doing cooling fins on your hybrid like the ones on Sean Colliers KX 500? I could get some of them done at the same time if they are a worth while add on?

The one in these pics was a dual piston set up.
Didn't net me any real gains and weighs more.
I just wanted to show you the possibilities.
I have a swingarm I have modified for a 450 rear wheel axle and rear brake mount and caliper.
I may or may not do the cooling fins.
To be honest, I don't need it.
I do not ride like Sean Collier does  Few do... 
He was melting down the stock caliper and pads in just a few laps because he trail brakes... A LOT!!!!
So, I made him that special caliper so we would never have to worry about it again.
So far, so good.
If you wanted to drill a hole in the top of your caliper to let some air through directly to the pads that would work just fine for most aggressive riders. The only issue is if you ride in a lot of mud.
If so, leave it alone as the stock caliper had more then enough stopping power especially when combined with the 450 rear brake rotor size.

I should have asked and not just assumed  was that a 10mm slice of alloy you added and was it just a matter of following the same angle that was used on the standard calliper mount to line it up with the disc in the correct position? Thanks in advance

I am trying to piece things together now, got a lazy boy head on its way to Larry for the de compression mod + all sorts on order, I will be ordering a second calliper mount for modding as will run the standard wheels as spares (Y)

Hi sandblaster, I purchased a low use 2018 KXF 250 rear calliper and mount thinking it would be a valid upgrade being 28 years younger?? I got it cheap so not a problem if not worth adding to my bike, I can sell on and hold out for a dual piston one if that is the best way to go?

I assume your one was a late 450 one? Thanks
