    shaft drives

    Hey the search feature isnt pulling up anything on shaft drives and I was wondering how much more difficult they are to work with. Considering using an old goldwing.

    The main issue seems to be gearing the motor to the shaft. You will need at least 2-1 to get the shaft gearing to the right ratio.

    I still really want to use a goldwing, can I use a hub motor and bypass the shaft drive nonsense

    I looked into it a bit. The only close to usable reduction ratio in a shaft drive is the early Moto Guzzi at ~4.7:1. All others seem to hover around 3:1 which would require further gear reduction to achieve the roughly 5:1 which is commonly used.

    I'm a noob at this so if there's a way to make ~3:1 work, then by all means. Hub motor = simple solution. I think my next build will be a hub motor...



    EDITED TO ADD: The early Guzzi shaft drive isn't bad for torque handling, but the later one does better. I think it would survive under an electric conversion given the infernal combustion engines which they backed to that shaft drive...

    I think ZERO is 4.2:1 I looked into this too with a Suzuki Savage.

    I have never had a shaft drive motorcycle but from pictures online it looks as if the shaft drive requires a special hub. am I wrong? Aside from that I cannot find any websites that sell hub motors for motorcycles that doesnt look fake.
