replacing my front end

[muad_dib_jb]

i have a 89 cb400f and i really cant get the front seals to seal i have replaced the left one once and the other one twice but both still leak.
well i found a cb900 parts bike for cheap and i m just wondering if i can take the front end off of it and replace my broken front end?

Here is how you find out.

Go to this web site: http://www.hondaparts-direct.com

Look up the part number for the CB-1 bearings. Then look up the part numbers for the CB900F. If they are the same, then most likely it will fit.

I already looked up the numbers and the bearings for the CB-1 and the CB900F (I picked a 2003 900F) are exactly the same. I am using a CBR929RR front end and the bearings are exactly the same and it fits perfectly in the CB-1 column.

I would say your CB900F front end will be a direct fit into the CB-1. You may want to look at getting tapered bearings for it though while you are at it.

I forgot to mention though. Check the fork height.

For example on what I am doing.

The CB-1 clip-ons go above the top triple tree. I cannot install the clipon this way using the CBR929RR front end. The forks on the 929 are shorter than the CB-1 forks. BUT, installing the forks so the top of the fork tube is even with the top of the top triple tree puts the the forks at the same distance from the top of the triple tree to the center of the axle as on the CB-1. The 929 clip-ons have risers so it puts the handle bars above the top triple tree and ALMOST the same spot as the CB-1 clip-on. The 929 handle bars are about 1/8" or so lower than the CB-1 bars.

So look at the fork length difference and measure from the axle center to teh top of the top triple tree and see where the CB900F forks will land.
