Itsnot an easy job as the original sliders only have mounts on one side, easiest is probably a 400 superdream, but that gets you a comstar whell

but does the yokes fit 400/4 frame because the superdream forks are bigger so wont fit 400/4 yokes

Don't remember thw 360 having twin discs, i think it was identical to the 250, and the forks were identical to the 400/4

Yup, but thats the problem as none of the UK models had that fitting. having said that the first 500 i twin disced i fitted two LH sliders and had one caliper in front and one behind then modified the mudguard mount. Worked fine even tho it looked odd

I used the front end from a CB500T for my twin disc setup on my CB550F, keeping the standard gatered forks for my Winter setup with a single disc.

But i've seen a pic...somewhere...of a set of 550 forks being used on a 400/4 with the 400 discs & caliper brackets installed so as to keep the front end not over braked

Found these tasty pics of a Bimota 400/4

Yes BUT the forks are a bigger diameter so you need the yokes as well

CB400n forks are 33mm diameter - they should slide straight into the original triples.

500 or 550 hub, laced into an 18", 40-hole rim keeps the speedo setting nice and can take two discs up front.
