Re: Hello From Sonoma County California
We have had pretty good luck with the Moped hubs, specifically the Puch hubs (supplied by Leleu) work well with the Morini motors, the stock offset was a perfect match for my Morini, I suspect it might also be good for the KTM, but measure for yourself. Sprocket sizes were pretty limited, but my brother Pat now makes custom sprockets for these hubs. He also bought a huge lot of NOS lelue hubs too.
The brakes are not as good as some of the modern disk setups I have seen, but the drive sprocket and bicycle sprockets are bolt on pieces which makes them very convenient.
