On my F3 the rebound adjuster is jammed. Its cheaper to buy used forks than to buy new adjuters (about $170 each). I want to research putting a F4 fork on my F3. This would give me bigger calipers and a compression adjustment.

I need someone who owns a F4 to measure the length of the fork from the axle centerline to the top of the fork tube (not including Preload and rebound adjusters).

The reason I want to know the length is that I want a fork with the smallest geometry change.

I know the triple tree would have to change.

Thanks

 

I've already done this for you in the same post you made in the F4 section here...

I don't see it. I see a seat conversion and a f4 vs f3 subframe.

 

Click on "F4 fork Conversion on a F3" in my post above. It takes you to the thread you posted in the F4 section, which is the same as this. You'll find your measurement there.
