Front wheel collar KDX250

Post by Huffnpuffer » 05:57 am Jan 24 2018

I have a jap 93 KDX250. I have just brought some new bearings for front and rear. I was sent 2 seals for the front but the front only needs one. Problem is tbe collar on my 91 has a 20mm collar and my 93 has a 22mm collar. The seal dosent fit my 93 as the seals ID Is 20mm Not 22mm. I wondering if it may be the wrong collar for my 93. I want to put it back to factory oem. Anyone know what ot should be?

There are 3 parts to a wheel.....Rim (what you are referring to for the markings) hub and spokes. Each of these are a different pn. It is very likely that every Kx/kdx with a did rim has the same markings as what you posted. The hubs may be different, as the could have been updated yearly.
For example, I can use any 89-06kdx rear wheel on any of the 89-06 kdxs, but there are some differences, like the brake rotors bolt size.
Hope that helps

5 93 is indeed the month and year

Is there a code on the hub?

It is hard to keep guessing without pictures, but I would assume someone changed something. It's not like you are the original owner of both bikes and know the complete work history of both.

F-1 240 is the only makings on the hub except, made in Japan. My 91 KDX250 rims are stamped 4 91 front and rear rims. So maybe a change in seals for that year or its not origional. I ended up getting 2 seals, 35mm x 22mm and a 35mm x 20mm which will cover me till I sort it out. Thanks for the replies

Some of the hubs on KX have the last four digits of the part number.
