Lowering Honda CB500 forks?
« on: February 04, 2017, 04:53:22 PM »
Hey!

I'm new to this and I'm looking for help!
I want to lower the front forks on my CB500k1, and have seen a bunch of videos on how to do it on the 550's forks.
As I disassembled my forks today (thinking they would be more or less the same), I saw that the design is a bit different than on the videos I have seen.
Is there anyone who has lowered CB500 forks with the same design as mine, that can shed some light to my problems?

Why not tell us what the difference is so we don't have to guess?

Well, I'll try to describe it as good as I can.

On the 550 forks, the piston sits inside the chrome tube. One way to lower the suspension, is to put a tube/big washer between the piston head and the small spring (BLUE ARROW), which makes the piston sit further in in the tube.

On the 500 forks, the piston looks totally different.
The piston doesn't sit in the chrome tube, which makes the idea of a tube washer an unfitting technique.
The only way I can think of lowering the suspension with this design, is to:

* Shorten the rod at the top and make new threads,
* Cut the spring the same length as the rod is shortened
* Cut the chrome tube at the bottom and lathe the inside a little bit (originally it is, but by shortening the tube the lathed bottom end will be cut off), so that the bottom end of the piston fits inside (which it otherwise won't).

Is this really the only way to shorten this kind of suspension?

Would be easier just to buy new forks, but those kind of forks aren't available everywhere here in Sweden..
