I have since found out that the NC29 hub width is 155mm without the Cush Drive, which sounds like it might be in the ballpark, next I need to find out how wide the overall assembly is, my RS250 wheel is in the region of 178mm between bearing faces. Oh, I also found out that the rear disc is 220mm

whereas the CBR400 (NC29 gull) rear is 17 x 4.50

can someone confirm
yes, the NC29 is 17 x 4.50, just got hold of one and will try to fit it in my KR1S-swingarm. The 160/60ZR17 tyre just about fits in it.

The width between the bearing faces is approx 183mm

How heavy are these wheels?

I measured 13.9kgs on the Mrs' scale, including tyre (Dunlop Sportmax D207 160/60ZR17), brake disc, sprocket and carrier. Will weigh a KR1S wheel tomorrow for comparison, as I haven't got a clue how exact this scale is..

Just a comparison is fine if its lighter its a winner as far as I am concerned, is it the same wheel as the 91-94 cbr 600 as they were a 4.5 rim as well.

You might be correct, I just compared the partnrs of the CBR400 and the CBR600 rear wheel on cmsnl and they're nearly identical: 42650MV4305ZA and 42650MV9305ZB
