Hi phantom, if you want a nimble and good handling bike, leave the standard suspension on an mc21 and get it sorted by a suspension specialist and it will feel much better and handle better than any modified mc21 with u/side down forks and single sided swing arms, how do I know?, iv'e rode both at trackdays for the last ten years and a well sorted standard mc21 is sublime. Good luck with your efforts.
Couldn't agree more, Les!
The 1991 NF5 RWU front-end I ran for a while was great, but it certainly wouldn't be to everyone's taste, and would be a very expensive option these days. But well set up RWU forks are the way to go.
A good "conversion" would be later adjustable NC30 forks. They are a cartridge type [similar to the MC28], and also allow you to run the larger 296mm discs that some people like. (NC30 or modified MC18/MC21 calipers required.) They're the same 41mm diameter as the NSR, so slot straight into the standard triple clamps, therefore maintaining the stock geometry, and can be used with the NSR or NC front wheel & spacers. Note: Be aware that some NC30 forks are similar to the non-adjustable NSR "R" model forks.
Rear wheels and tyres need to be taken into consideration with a Pro-Arm conversion too. While NC30 swingarms and corresponding 18" wheels are pretty cheap and easy to come by, RVF400 and MC28 17" rear wheels are expensive, and considerably scarcer. An 18" wheel and incorrect suspension geometry can easily and radically alter the MC21s handling for the worse, and the choice of decent rubber in 18" is also seriously limited.
What would be shame, in my opinion, would be to modify a very capable chassis and turn it into [maybe] an acceptable one, having never known just how good well set up stock parts can be. I think there are a lot of modified bikes out there that fall into this category. Of course, if you're only ever going to ride it down to the local bike night to display, then it doesn't really matter how bad it handles.
The NC 30 was my friend suggestion to conversion method since he have stated that it only be needing some few alignment and machining to fit it all perfectly without a hiccups.
The pro arm he also mentioned that he'll be going to source out a direct "17 pro arm set either in UK or Japan.
I might enter on a "Motorcycle show" in my area showing off the NSR lovely looks,sounds specially its dry clutch sound and also for a good nimble bike to use.
