I know that you can use CBR400 nc29 front wheel on CB-1 forks. From that logic you should be able to use that front end in your CB-1 yokes, but there will be issues as that bike has 296 front discs. You'd have to run a single 296 and the CBR's are too thin as they are to be used as a pair. Also the forks will probably be shorter as the handlebars go below the yoke on that. I tried that once and they clobber the tank
Errm, short answer is "probably not", then.
You'll probably have more luck with a set of fireblade forks. 98-99 has 41mm forks which are likely longer than the 400's and 310 front discs so with those forks plus the RHS caliper, with your wheel and disc and some spacer-ing, that should work. That caliper is relatively massive (32+34mm pistons versus CB-1 at 27+30mm), you'd probably want eg. a brembo 13mm master cylinder like off single disc 600 monsters and cagiva planet not the CB-1's 11mm - that just won't work.
I have a 98 blade so can take measurements as much as you can without dismantling stuff, but it's in my folks' garage so can only visit it at weekends. I could do with doing that this weekend anyway. Also a 98 blade weighs approx what a CB-1 does for the spring rate, and you'd have the full adjustability on what I have heard called the summit of evolution on RWU forks.
Anyway, might be best to try and find CB1 forks unless you were already looking at upgrading
Can you tell from this post how my mind works, and why my Divvy ended up with Revere hand levers, my old 96 fireblade with an 00 seat unit, and my CB-1 with a CBR400 swingarm? Amongst other various mods I've made to pretty well every bike I've ever owned.
