Default Showa 47mm Twin Chambers on a '96 CR250

OK, I have seen the swap mentioned, but I can't find any details on exactly what parts I would need to install Showa 47mm twin chamber forks from a newer CR on my 1996 CR250.

I assume it's a given that I would need triple clamps. Will the steering stem slide right into my frame or are modifications required? What about the wheel, axle, brakes, and front fender?

Any help would be appreciated.

you will need the clamps,axle and spacers from the 97-and up forks. the front wheel should work, but i am not 100%. if the front hub is bare aluminum, chances are it will work with twin chamber axle.( i have seen some here that, for some reason, use the older black hub).... look up your front bearing part numbers, and cross ref. them to the 97 and up bikes.
FWIW, i have a set of clamps if you are interested in the swap...

2000 and 2003's went right on the 93 frame I am using using the newer triple clamps of course. I can't exactly remember when Honda went to the 20mm axle, but I want to say it was 95 or 96. just measure yours. if it is a 17 mm axle then you need another front hub or wheel. early calipers fit on the 03's that I have, but of course won't work on the 04 or after forks do to the difference in offset at the axle mounts.

Thanks everyone. It looks the Showas didn't change much internally through 2007, so I'm going to pick up a set from an earlier model and do a full Race Tech install before I put them on the bike.

The earliest I have personal experience with were on a 2000 cr 250. I was very pleased with them. I then got some from 02 and 03 and could tell a noticeable difference. I have ridden plenty of bikes from the 04 and newer years, and was equally impressed, but I don't know how much of the better feel from the front end can be traced to the forks themselves. I have put the 02 forks on a yz125 which had 03 yz forks before the showas, and I think it is a big improvement. The 02's and 03's were tried on the 2000 my son owns and were better the way we bought them than his were (modified by a well known and advertised suspension tuner, but worn).

You don't have to rush into anything of course. I don't think I paid more than 225 for any of the sets I got.

After cross checking part numbers (both OEM and aftermarket) for various model years, I pretty much have concluded that the differences are mostly in the valving, which I'm going to redo anyway.

I owned a 2001 CR250 and a 2007 CRF450 simultaneously for awhile. After changing the fluid, installing new bushings/seals and the correct springs for my weight on the '01, I found that the difference between the 2007 and the 2001 was negligible (at least at my skill level). I did spend a fair amount of time with both bikes getting the suspension set up correctly, which is probably more important than any changes Honda made to the forks between 2001 and 2007.

My current '96 was revalved by Pro Circuit for the previous owner. There's a "Works Kit" (not sure what that was back in the day, but the internals appear to be stock or close to it) sticker on the forks, along with a PC sticker showing the previous owner's name, comp/rebound settings, and spring rate. I've installed new bushings/seals, changed the fluid, and installed the correct springs for my weight. I plan on throwing the Race Tech catalog at the Showas, so it will be interesting to see how they compare to the PC KYBs when I'm done.

I have a set of 04's sitting on my cfr 250, I have thought about putting the whole front end on the 2000 for a day, just to see what the differences in offset would bring as opposed to the 02 or 03 forks. Just haven't done it yet. I am sure you are correct on the differences being in the valving. I am just not as quick to spend money lol. None of them came with enough spring for me either, but that is easy to fix. Most bikes don't in that respect.

Sounds like you are really going to like whatever ones you end up with though. I have had some Racetech parts and work done. Maybe it is just because one of the founders is an alum of mine (as is Terry Davis) but I have preferred their original shop's work to others.

Do you have any plans on swapping the shock for a newer unit?

Post an update once you get the forks installed. Sounds like a neat project.

the 96 shock is a lot shorter than the newer ones.

Installation complete. '98 CR250 forks bolted right into the stock '96 triple clamps. I didn't have to change anything else - plastics, axle, brakes, etc. fit perfectly on the '98 forks. It really couldn't have been any easier.
