CB360 front wheel on an XS400?

    I searched, couldn't find anything... would the front wheel from a '75 CB360 swap onto the 81 XS400 for a disc conversion???

    It looks like the CB360 has a 15mm spindle same as the 400. Anyone have any insight?

    Thanks in advance!

    If this bike doesn't have disc front then where will you bolt the caliper down? And is the speedo cable fit and ratio the same? Likely not and not worth the effort. Why you're not finding anything.

    That's unhelpful. I have XS400 forks from a disc brake model, as well as a disc, brake lines, and a master cylinder. I am looking for a wheel and information about a wheel only, hence asking if this particular wheel shares the same spindle diameter and thus would be an easy fit. Plenty of people here convert their bikes to disc brakes by using wheels from other bikes. No need for discouragement.

    'I have XS400 forks from a disc brake model, as well as a disc, brake lines, and a master cylinder. I am looking for a wheel and information about a wheel only, hence asking if this particular wheel shares the same spindle diameter and thus would be an easy fit.'

    No THAT'S unhelpful. Your inaccuracy in posting detail avoided any mention of it. What I gave you was reality, and I filled in much detail you didn't give a thought to. You can use a nuclear reactor from a battleship in an aircraft with enough effort and money poured into the money pit, that doesn't make it practical.

    Your locked-in thinking about axle size only is still too limited even for wheel ONLY, you haven't taken into account the spacing of disc, the diameter of disc or wheel centering issues in fork and why are you even talking about wheel 'only' if a disc is also involved?

    And you still have the speedo issue to deal with. Will the cable fit? Will your speedo read right provided the drive ends are even the same? What if your axle is not LONG enough? Does one screw in and the other clamp? Is the axle stepped for it?

    '...spindle diameter and thus would be an easy fit.'

    Who said that, you? That is a lackluster determination of go or no-go there on a disc setup for sure. The equivalent of putting a 426 Hemi in a 289 Mustang, they both are v-8, why doesn't it fit??? Pretty funny actually.

    I'd hate to see you mod internal engine, with your narrow mindedness you will blow up every one you work on.

    Discouragement? I have no need of optimism, it breeds the shortsidedness that commonly messes up things in the world. It is also what blindly leads people into brick walls at 100 mph. I deal in pessimism, it allows one to see the problems (the brick wall) others gloss over saying they are 'easy', while I am the guy actually figuring out how to make those things work and stay that way. How I made a living for 35 years both running and repairing 100 foot long printing presses with hundreds of thousands of parts and you keep talking about just one silly measurement.

    It's always been hard for those who try to turn everything optimistic to pick up on discouragement often actually being reality. When It finally doesn't work instead of going crazy I for one will likely already have a plan for making it work while the optimist flips out when the unforeseen consequence happens. NOTHING is unforeseen, it's overlooked in the optimism instead.

    Wrong. My question is if the particular wheel would work. A helpful response is “Yes, if A, B, and C.” Or “No, unless you also had A, B, and C.”

    But nice try.

    Your exact words OP...........

    '...would the front wheel from a '75 CB360 swap onto the 81 XS400 for a disc conversion???'

    Say the axle is the same, then it swaps, that does not mean it works. The outside parts A, B, C, (which I had to drag out of you), must be qualified to work or it doesn't work, you either get that or you don't. Knowing whether a thing doesn't work can be just as valuable as knowing it does.

    I suggest you not slice english with me, I had past college exit english grades in the 7th grade, I'll cut you to ribbons using your own details to do it.

    You know, I came here for help. Take your insecurity elsewhere.

    More.............the 360 Honda wheel must flip since the disc is on the left and the Yamaha is on the right, the speedo drives swap sides too and are opposite the discs, meaning the Honda speedo drive will run likely BACKWARDS trying to drive the needle below zero. Haven't found the Honda speedo ratio yet, the Yamaha is 10/17. Not common for those drives to swap out but one can always check.

    I'll even apologize as I can be an ass but not often an incorrect one. It is what it is. You should know that beyond the printing where I commanded press crews for all those years was years of racing both 2 and 4 stroke cars and bikes and so much parts swapping you would not believe it. We drag raced American Motors cars and you had to make parts the Ford and Chevy guys could easily buy. I was lucky enough to get to play with 1500+ hp. pro stock cars too that ran over 200 mph. Did a lot of playing with '79-'83 Honda DOHC fours too.
