    Default 70s -80s 17 Spoked motorcycle rims?

    Hi guys Im reaching out to all you motorcycle fundies. Im looking for a relatively
    common 17 spoked rim thats was used on old motor bikes back in the day in South Africa.

    Something similar to these comes to mind.


    The important part is that they have to be 17 and spoked vintage style.

    Something interesting regarding the engineering concept of that type of spoked wheel is that, due to the spokes being in tension, the hub and thus the weight of the vehicle, actually hangs on the spokes from the top of the wheel.

    When I wanted a school holiday job in a motorcycle workshop, they owner gave me a rim, hub and spokes. I had to assemble all and the wheel had to run true horizontally and vertically with all spokes at the same tension. I don't know how I managed to do it.

    Hi Viper. Im assuming that you know of The Bike Hospital in JHB central, they have thousands of wheels, might well have what you need..

    Im going to try and build something along the lines of this. What they call in the states a cyclekart. Its becoming quite popular. They base there scaled versions off designs on vintage Grand Prix cars, but its not limited to that.

    Its so popular that they even host races. Looks like great fun. The build is also not that expensive.

    They run a Honda GX 200 motor in conjunction with a comet clutch.

    Its seems the reason for using the 17 rim is for scale. They prefer the Honda ct90 or 110 rims because they can easily be converted to accept
    The right shafts



    Yeah Im planning on going to bike hospital today. But I was hoping to use a bikes name instead of asking for a 17 rims. I can just imagine what looks Im going to get when asking a questions like Im loooking for four 17 spoked rims... for which bike?

    Ugh... Bentley Blower or Bugati type 35B maybe?

    We dont stock those sir.

    Damn thats beautiful, best of luck with the project, please post progress along the way if it comes to be..

    Back in my off-road days I used The Bike Hospital a ton, very helpful (then) and always allowed me and many others to search unabated so I think you will be ok..

    Thanks, I will create a new thread once I have enough material so that not months go past between posts. But its going to be slow build, I guess, seeing thats theres a couple of other project on the go as well.

    And my biggest problems is choosing the car of that era to build theres so many interesting and beautiful shapes.

    18 inch or 21 inch would be easier to source IMHO.

    These were the common sizes for enduro and MX bikes since the late 70s.

    17" is as you say, more related to the entry level off-roaders and those things just don't get sold in enough numbers.

    Yes, I sort of came to the same conclusion. Wasnt there a common delivery bike that had spoked rims?

    But I recall reading somewhere that certain hubs were problematic. Guess Ill have to do some more reading.

    Might come up with a better as what works in the US might not work so well here

    I'd try and buy something with disks already fitted. Fitting a set of calipers on a custom bracket will be very easy. A simple pedal adapter for a bike master cylinder will be just as easy.

    Drum brakes on bikes were shyte, regardless of how you tried to make them better. And getting the drum mechanism located means an arm or a slotted hub which makes the entire setup ugly.

    So I made my way to Bike Hospital. Ive known about it for years even drove past there a couple of times but never really had the need to go in.

    Man what can I say that place has parts not for days for decades. Its a complete mess but yet you still somehow end up finding what you looking for.

    Spend about an hour and a half sifting through rows and rows of rims eventually ended up with 12 rims that were all similar but yet different some more damaged then others.

    I wont say it was a steal but I guess they also need to make their money, but ya paying 500 bucks for a rusty wheel is not quite a bargain,

    Anyway this is what I ended up with. Decided to go with the original plan of 17 wheels




    Guess my next question would be, how the hell do I restore these?

    Should I disassemble spokes and then sand blast?

    Not really an expert at Balancing rims, but if that is what it will take then Ill have to do so.

    Give me some suggestions?

    Time to make an English Wheel for the body panels if you don't have one.

    If you want black or chrome better to talk to company who does the work. They will tell what is needed. I do not know if you get spare spokes so better to keep count.

    I have tried to get bicycle rim and spokes right Some bicycle shop will get the rims right if all else fails.

    ViperR glad you came right at bike hospital..

    Back in the day My mate and I used to ride Honda CR500’s, he knew one of the guys there, and one day rummaging through their many crates and boxes he found a brand new CR500 motor in a trommel, which they gave to him for nada....

    Man was I jealous...

    So my little contribution to this project, if you want that is.... My spoke tightening tool from a back in the day, should you want to pull those wheels apart, much much better than using a small shifter for the job, won’t deform or round the spoke nipple..

    The tool is designed for 6 different size spoke nipples, if yours are bigger you could open her up a little with your mill..

    Anyway, yours if you want...
