Look up bearings with the 09 CRF i.d. and 1996 o.d and depth, very easy info to find. If I remember correctly the i.d. of the Honda bearings is the same from 1990, or so, to present so the 1996 bearings should be fine, yet my memory could be failing me.

Bottom is the same. Top is a little thinner. All balls sells the bearing and seal plate to bolt it in.

I have had troubles with their page too. If you close and reopen in or refresh a few times it will eventually work.

I thought the fork swap required pressing out the 96 stem for use in the new clamps? Do the modern clamp stops line up to steel frame headtube lug?

You don't have to swap the stem with the conversion bearings ad shims from All Balls. The steering stops can be remedied by either welding a little bit of material on the steering lug of the frame side or drill and tap a set screw in the aluminum lug of the lower triple clamp. Others have just left the stops as is and have not had any issues.

Yup that's what you need. No need for the bottom bearing unless yours is roached. 06 clamps and 09 front end on my 91. Smile

Don't mind the number plate as I just didn't get to adapt my 91 plate in time before the last race. Lol

What does the 91 ride like now?
Is the fork length the same on both forks
Or does front sit high

Still in the testing and setup phase but they are close in length and the handling is razor sharp. Smile

I've done this conversion, i swapped the stem and bearings from the 96 onto the newer clamps. Dialed, nothing else needed.

IDK about same length but its definitely the correct fitment, due to different frames i never measured length of stem. I had both sets of clamps laying around so it made it easy. Pretty sure top nuts are identical, again i had both sets to make it work so it could be off either one.

Yes. My picture above is a 91 CR with 07 CR clamps. Just a new top bearing and spacer to fit right in. Smile

I had a look again. Looks like it is the same bottom bearing as the 1991 and you just need the Top Bearing to fit those forks. PN. 99-3540-5.
Wow. That bike looks like a basket case. My project CR250s are much the same. It is amazing how bad people run this stuff into the ground. Just destroyed. A little maintenance here and there and these bikes could have still been running. I love the restoration and find it quite enjoyable to do but sure wish it didn't cost so much. Good luck.

If you need the Bottom Bearing you would need PN. 99-3510-5.
I noticed that All Balls site shows the top bearing PN. 99-3540-5 out of stock. It does list the dimensions. Maybe you can find a bearing at a local bearing shop. Here are the dimensions. 99-3540-5 is 30mm ID, 47MM OD and 12MM wide. Good luck getting it together.

Looks like you have a few projects there for sure. I love these bikes. All those Honda models from 86' to 96' are my favourites. I especially love the 88' to 91' 250s as that is what I raced when I was a young lad. I am building 2 88's right now then a 1990. All 250s. I would kind of like to do a 1989 to 91' 125 as well if I can find the right one. Thanks for sharing.

Cool. Would love to see some more of those bikes. I love them all but always loved the Honda's of that era the most.
