Well, ZX-25R already has USD forks so there’s no way the ZX-4R isn’t getting that. I do wonder if the upgraded suspension is going to be an Indonesian exclusive but the website doesn’t say anything like that:

So, yeah, we might get a double-R version of the ZX-4R as well but maybe with a bit more to distinguish it, Perhaps the second front disc brake will be an RR-exclusive (hope not). One thing is for sure: It will weigh MORE than last year’s ZX-25R by virtue of the bigger exhaust and second disc brake on the front. There just isn't any getting around that without building a whole new bike... which they aren't going to do until they've squeezed a lot more out of this one. Even then, we'll have things like ABS (soon mandatory) and emissions weighing them down compared to older bikes.
