Zx-9 usd front?

[Guest]

I know the kawi guys use these for their length on kz1000 swaps and was curious if anyone had tried them on a GS? Early 90s usd GSXR forks are hard to come by, and these zx9 forks are a steal. Is it as simple as pressing the stem out, is there more to it?

i have a build on the go using the 46mm RSU ZX9R forks, they are longer than the USD's

I think the usd length is almost spot on with the stock gs1000 forks. Just needing to know if anything needs machined or if I could just swap out the stem, put in new bearings and be good to go.

Rich Desmond posted this comment on another front end swap. Good advice of things to consider when doing a swap like this. Rich knows his stuff, he owns Sonicsprings.

"What are your goals? If you're seeking a custom look, then what you're proposing makes sense. If, on the other hand, it's a purely functional improvement you want, then I think you're barking up the wrong tree. Far better to spend the money on springs, oil and emulators for the forks, and a set of Ohlins shocks for the rear. Good pads, SS lines and a good bleed job for the front brake.
Just throwing more modern parts on an older frame, without understanding what effect things like triple offset, fork length and swingarm angle will have is likely to result in a bike that may look cool but handles no better or even worse then the stock bike did."
