Zxr400rr usd forks compatibility

[Kawasakifan2508]

Got a 1997 zxr250 I’m working on and forks are shot. Found a used set of zxr400rr usd forks and they appear to be the same. Anyone know if they’re exactly the same or not. Cheers

Hi there, ive got both bikes, the forks are different.

For example the 400 forks use 3 points to attach to the mudguard, the 250 forks only use 2...so you might need to cut that part off.

I can't get into the garage at the moment, but I'm wondering if the spindles are different diameters as well, hence the lower clamp wouldn't fit.
