hmm... I don't think they will. They bolt straight to the 28 fork legs for sure but I know that the 28 calipers won't work on the 21. (this is all from my warped memory so don't take it as gospel!)

The MC21 caliper is nonthreaded mount the lower fork leg is threaded, MC28 is thread mount caliper, lower fork leg is straight thru hole. You could install MC28 lower fork legs on your MC21 and then us those calipers. Alot of work for cosmetic gain ? Why not go with Brembo's ?

if you use the brembos with the adaptor brackets
you could use your nsr calipers on the 29 by fitting nc 30 fork bottoms (£40 by mr france)

Is it true that the CBR600RR calipers bolt straight on to the MC28 forks? If so, wouldn't those calipers likely be an actual upgrade, i.e., work better or at least be lighter, rather than just bling-bling?
Cheers,
Jim

Yes, the CBR600RR calipers do work on MC28 forks. That's what I'm currently running on my MC21.

Being as I use the rear brake quite a lot, I have never suffered the problem.

I do pop the pistons every time I replace the pads though, give everything a real good clean, and polish the pistons.

Yeah, I know someone who like to use bushes to slow down... personally, I prefer the traditional method of using the brakes!! :)

Nigel, check the box "Disable BBCode in this post" is not ticked, then your [quote] tag will work.
