Topic: SOHC Honda CB750K Rear Hub

[MikeSB6]

Hello,

 I'm thinking of fitting A Z1000 accessory swinging arm to a CB750K, but the hub will be offset about 1/2" to the right, as the accessory arm is narrower. I was wondering about machining off the end of the sprocket carrier housing for the the oil seal and bearing retainer plate down the the bearing, and using a sealed bearing, which will allow the hub to move to a central position. As the bearing is retained in the hub by the axle spacer (I can use a thinner one), is there any reason while this won't work?

     Cheers, MikeJ

Hi Mike, sounds like a nice project. Are you installing the Z1000 Swing arm for looks, or function, or both? It must be a rectangular box type swing arm, which should perform better, but can you post some pictures of it, and your bike? If you have it installed, I would like to see the relationship to the sprockets and clearance you have. If there is a will, there is a way lol... Also, what year is the Z1000 swing arm?

Hello Charlie,

    thanks very much for the reply, it's a question of what I had in the loft but it's an old Bimota swinging arm, so should be sturdy enough and looks nice with the chain adjuster plugs at the ends of the fork. It's not installed yet but I've done some measurement and think I can get away with spacing the sprocket to the left and doing the same with the rim, as the needed offset is only about 6mm after measurement. I'm not sure of the year but I think it's probably K1-K6 as it's for the drum rear setup. It'll need the swinging arm pivot bore reduced to 14mm to suit the bolt but the rear axle size is the same.

I think you should really send that to me, and I'll get you a stock one for your bike. Then you won't have aaaannnnyyy fitment issues  Least I can do for a stranger
