After getting as far as I can with the 91 CR 250
That i am doing,
i decided to grab this
sad looking bike out of my shed
that has been waiting a while, Photo
and give it a new
lease of life!
Another one I bought in Spain
that had been left for dead!
I will rebuild it to original spec
with a nice pipe and better suspension.

Surprisingly its not in bad shape
when I stripped it out
with every bearing on the
bike in perfect shape
and underside of frame is like new!
Engine needs full rebuild and
a bit of welding where the clutch cable
goes into the case, Photo

dont think ive ever seen a worse candidate for a rebuild. If you can bring that thing back from the dead, you may start a religion.

I love the early '90s CRs, and will be following this thread.

I took mine out of storage a few weeks ago, and it's currently at Boretech being brought back to a decent condition. A US import, she seems to have had a relatively easy life (the forks still have the Showa warning labels on them for example). She looks better in photos than real-life, but I want something useable not a garage queen.

OP, am I imagining it or did you put a newer CRF front end onto a 1991? Much work required?

Hi AK74,
your bike looks in super condition!
Ive put the crf front end into a 1991
cr-250, that we used at Farleigh last year,
you can buy the bearing adapter
kit from Allballs, ive got ref no if
you need it

If you could share the reference number I'd appreciate it. From memory, the CR's front suspension was frequently cited as a weak point in the '91 125 shootouts.

1991 CR Hondas were great looking bikes and just great bikes all around. Looking forward to see how this one comes together.

Nearing completion. Just needs chain slider and chain, and then it will be time to ride.

What year CRF forks worked? Did you have to swap to CRF clamps too? I have a few of the 1991 CR125’s I’m starting to build and would like to update the forks. Thanks!

Pretty much any of the 97'- up 47mm Show twin chambers will work and generally the newer the better. Often you need to use the CRF clamps, front wheel or wheel hub and axle. You can fit the later CRF clamps with the "All Balls" bearing conversion kits. Check the diameter of your 91' steering stem as well. Some years are the same diameter so you can then press the 91' steering stem into the lower CRF clamp and skip the bearing conversion. The later forks are a great improvement and well worth the money. I only spent $300 for everything fitting 2001 47mm twin chambers to my 1988 CR250 with careful shopping I found a really nice set for a great price. Good luck with your projects and post up some build info for us.

Greg, thanks for all of the information. I’ll start shopping. I’ll put up some photos when I get home in a couple months as work has me on the opposite coast as my garage.

Ive got a set of CRF forks and BUD clamps for the bike
And Ohlins shock
I’m anodising the clamps tonight
In factory dark brown
They were faded with the sun
So we stripped them and Ive buffed them up
I’ll have finished pics tomorrow Photo

It had a chrome plated FMF fatty pipe that was toast!!
A lump of rust really
After an hour of bead blasting it looks fine
I’ll blow out the dent next week

Also anodised the cylinder covers
As they are bad quality alloy you don’t have many

So I managed to find a set of new rims
That we’re on offer
But in black !

Ive always liked the 85-87 gold
Which is supposed to be unavailable now.

Well I took the black rims to work
Stripped them

And now I’ve had them anodised I. The
Retro 85-87 gold !!!

The stickers even stayed on the rims which is a bonus
