120mm fork on a 1997/8 King Kahuna - is it safe?

[Monkeeee01]

A quick search on here suggests a ‘98 z1 Bomber is 450mm a-c and Fox F120 is 490mm ish.

I’d say an F100 is the limit at 470mm a-c.

Thanks mate!

The longer fork will be fine, as already mentioned it will only really affect the angles. You can always run it with more sag as well.

Thanks @mk one

Seller has offered to reduce the travel to 100mm for me before shipping - would that be the best option all round?

As long as the travel is lost at the top, so the fork is 20mm shorter fully extended.
Sometimes travel reduction is at the bottom of the stroke- which wouldn't be helpful here.

Seller has just advised:

“I have reduced the travel so 20mm is lost from the top so is now officially a 100mm fork!”

So I think I’m all good now

(Unless anyone tells me/thinks otherwise?)

Go for it.

Go for it.

Thank you

Bit late, but I ran a '98 Z1 on my '97 Cinder Cone without issues. Probably for a couple of years, around BMX tracks, jumping down steps etc. Great bike and the forks worked great on it.

@Monkeeee01 - why not try the SID you have first?... it looks like it may be at 80mm travel atm, but by removing the internal spacer it'll be 100mm.

When I've fitted forks that are too long for a frame, the steering loses it's smoothness - it hits a point where the bar and wheel quite quickly "drop away".

It would probably be worth experimenting a bit to find what you like/are happy with.

Cheers
