Here's a fork conversion I did using a 2007 KX250F front end. The stem bearings are the same, just the 07 stem is longer and the stops are different. A few others have done this conversion by replacing the stems. My press didn't feel like putting out the strength, so I found another route. The 07 forks are two chamber Showas and are far superior to the 8 year old KYB's.

07 KX250F triple clamps. Same bearings as my 2000 KX250. When I compared both trees next to each other the 07 stem was slightly taller...like a 1/4". So I just tapped (a press would be better but mine is too small) the stem down about 1/4".







It seems when you press the stems in you should press them in flush with the bottom of the clamp. So I just went a tad farther.

Only question now is the stops. I'll have to address that after I perform my initial install.

Once the stops are taken care of, the rest of the suspension will bolt right up.

Front end removed from the KX.



And the 07 clamps installed. You can see where the steering stop needs modification.





Fork tube to frame interference.

Here's the temporary stop I made up. I'm planning on refurbing the bike (paint frame/plastics/graphics) so I'll weld something on the frame for a stop. In the mean time...













not exactly what I wanted, but it will work for now. All clear with the frame, time to mount those forks.

Here's the finished product. I needed to use the triple clamp, forks, front brake system, wheel, axle/spacers. The 2000 fender bolted right up, but the numberplate is different. So I'm not sure whether I want to go stealth-like or not.







The first ride was awesome. The forks realy make a difference. I had the KX forks rebuilt and revalved by a professional and they still don't come close to the newer stuff.
