Vintage Dirt Bike Q & A

I'm going to install a 83 CR480 front forx and triple clamps on my 79 CR250. Does everything "fit"? Do I need to change out the stem? How about the axle, spacers and front rim. I want to run my CR250 rim. Will the CR480 double pull brake plate fit my 250 rim as well? Thanks T

If you use the 1983 triple clamps without changing the steerer tube you will need to put a large washer as a spacer on top of the upper bearing and under the top triple clamp. You might be able to transplant your 1979 steerer to the 1983 lower triple clamp. I did, but I do not believe I have 1983 triple clamps - but some other 43mm kind. If you use the complete 1983 front hub it will - of course - fit the forks and axle. You can lace any rim of the appropriate width and spoke holes to the hub. I went with an Excel.

this is only possible with the 1982 tripple clamps.
the 82 and 83 brakeplates fits only in the hub of the same year. they are not interchangeble with others.

I changed out the stem....hydraulic press recommended.

Going to press out the stem and install into the 480 triple's but still wondering if there's a way to utilize the 79 CR250 complete wheel. Going to check into axle, bearing's, spacer's, etc. Just wondering if anyone else has tried this.

You can use the complete 1979 CR250R front wheel / brake set-up with 43mm Showa forks. (I have seen it done by a CalVMX competitor.) You'll need to experiment with the older / newer axles to see which one centers the wheel correctly.

The reason I was able to transplant the 1979 steerer was because my recipient 43mm triple clamps hold the steerer with a clamping bolt. My understanding is the 1983 steerer is held in the bottom triple clamp with a form of clip. This may stop you doing what you want to do.
