Any newer USD front-end will compromise steering on the NSR, especially turning right, as the forks will foul the radiator. (The radiator cap fouling makes right-hand lock even worse.)
You don't say which model of MC28 you have, but you could do a lot worse than use refreshed original MC28SP forks. HRC springs are also available for them if you really need stiffer springs, but I suspects a good strip and clean, and new high quality fork oil will do wonders.
Of course, retaining MC28 forks means you keep the NSR wheel and brakes. A conversion often means a different wheel, new spacers, misaligned brake disks, new hoses, different steering stem, new bearings, etc., etc., etc. There's nothing you can just "throw on" without modification, so it depends on how much work you are prepared to do, and how much of a compromise you are willing to make. _________________ Andy.

A lot of owner in my country convert into RVF front end. They said when slow turning(like a U turn), the bike cant fully turn, meaning turning a wide angle...
So what can i do with my front end? Changed into SP kit?
For quite some time, I was never aware that the MC28SE and MC28SP forks were significantly different to each other, however the SP forks are a different design, and are better than the SE forks. They will most certainly (once refreshed) be the easiest upgrade for your MC28SE.
I personally would also expect an MC28SP setup to out-perform an RVF400 USD setup. The NSR's I've ridden with RVF forks just do not inspire confidence, although some other forum members have had success with them. I think an RVF swap is far from a case of just simply bolting them on though.
Regardless of how well you do the conversion though, you will always compromise the steering with any USD fork conversion. I run HRC RS250 USD forks on my MC21SE, and they are absolutely superb, but my steering lock is abysmal! I am prepared to suffer that, given the wonderful suspension I have now! _________________ Andy.

Andy's right. A well set up RWU NSR250 front end can be very good. The MC28 SP suspension offers a little more control on the adjustment. The rebound adjuster (on top of forks) also controls compression to a small amount. This is not so on MC21 forks or MC28 SE.
The RVF front end can be made to perform, and it does look clean and tidy. But yes, you do need to consider other factors such as disks and what have you.
As for RS250 USD forks...who needs steering lock when they look this good and perform this well.
