They’ve cheated a bit on the forks, they’re anodized gold and apparently tweaked but they’re still the Kawasaki units (Kayaba I think) not ohlins
The ohlins back shock would be nice to have especially for the remote preload adjuster and the brembo caliper should be good too
Having said that I’m still loving my “normal” Z900rs, it’s a brilliant bike, the standard suspension is plenty good enough and the Kawasaki branded radial brakes are excellent
Hope you’re getting a good part ex price against the SE ?
