Dennis, The offset between the bolt holes and the spoke holes is there for a reason. The bolts that hold the rings are mounted in extended material on the hub. If you don't keep this offset, you won't be able to mount all your spokes, because of the extended material on the hub. If you see the...

Hi Dennis, I suggest that you buy a set of front wheel spokes for a 750K, measure the spoke length, and use the spoke length formula, to work backwards. Use the inner ring diameter and the bolt circle diameter of the earlier post. If you have some measurements, I will help you out. The width of...

Cracking is possible for stainless steel rings, when you ride on salty roads in the winter. Stainless steel and chemical chlorides are not friends. This can be resolved when you coat your rings.

If you want to do that with your current wheels, it can be done, but it will not be easy, and if you don't have a lathe, it will be quite expensive. You will need to mount the spoke rings behind the brake discs, so the hub will need to be made smaller, and you will need to put spacers between...

Hi SmaRTrxxv, Thank you for your interest in this subject. In the interest of every reader of this subject, can I please advise you to clarify your measurements? You mention an inner dimension. Inner dimension of what? Bolt circle of what? If you can, please make a sketch, so that every reader...

Another thing about the drawing: change diameter 5.3mm into 5.0mm and 8.1mm into 8.0mm

mistake, omitted

Hi Foyil100, The '75 or '76 750F Supersport had hubs for spokes and brake disc, but these hubs are hard to find, hence, expensive. My method gives you a perfectly, technically acceptable alternative. I am lucky to work in the petrochemical sector, and our piping contractor has a programmable...

Soon I will post the final update. I will put everything here to modify your rear CB750F Supersport Comstar wheel into a rear wheel with spokes. Since I am deeply disappointed in the reactions to my post, I will silently modify my Comstar front wheel. If there are really interested people, they...

why not under the fuel tank, where the ignition coils are?

My next update: The standard rear spokes for the CB750K are still a fraction too long (less than 1 mm), so I used washers on the nipples. It will take some time for the washers to get the correct shape, so remember to regularly check the spoke tension when the rear wheel is in use. It's for...

nice find, good luck with your new project

Here's my next update after I received the rim: The inside diameter of the 18" WM3 rim is 430mm When I use the spoke length calculator with this new value I get a spoke length of 138,8 mm Conclusion is that the 1976 CB750F spokes are too long. Spokes of the CB750K are 142mm see...

You can do it yourself, read my post http://www.cb750.com/threads/2082-spoked-rear-wheel

spoke rings have arrived

Hey guys, Here's an update to my post. This is what I did sofar. I bought an old 18" 2.15 Honda rim for 10€. It will be delivered shortly. Since I got no new answers to my questions, I did some calculations, to determine the spoke length, using the formula on this site...

what is the spoke length I should order?

The rim will be a standard Honda WM3 rim.

I understand your comment, but it's not a solution to my request. The 'spoke rings' will be made of 316 stainless steel, which is much stronger than the aluminum, which standard Honda rims are made of.

I already have a dual disc CB550F front wheel to replace the ugly Comstar

Thanks for your reply, but I'll stick to my plan, because I already ruined the rear wheel.

The rear wheel is 18 inch, right? My mistake

Hey guys, I'm new to this site. I'm looking to build a cafe racer from this 1978 CB750F SS I hate these comstar wheels and I will try to modify the rear wheel into a wired wheel.

Hi everybody, I'm new to this site. I'm building a cafe racer from a 1978 CB750SS. I'm looking to modify the hub of my rear Comstar wheel, in order to make a wired wheel. Therefor, I need to know the diameter of the pitch circle of the spoke holes of a standard 19 inch rear wheel hub. I would...
