I was thinking, a Radial T/A with an off road tread, or perhaps a snow tire type tread, might be the perfect tire for the 50% off road / 50% asphalt rider. Longevity must be around forever. It has a steel belts. It is designed for the weight of car -- probably could ride it flat if you had to. To bad the fit is off. I bet it would be a big hit in the TW world if it could be safely done.
Is there any way to mount a car rim, the outer part, to the TW center using spokes? How difficult could it be? You know, make a custom wheel. Somebody must do it.
Like I said, been there, done dat. Done it successfully here and there with some big road bikes in the past but the learning curve was a bit expensive. Gave it another shot awhile ago on the TW:
What Gizmow is saying is that the only way to do it right (if a squared-off car tire that climbs its own tread face and changes trail like light switch could ever be said to be "right" for a motorcycle, anyway) is to give it a proper rim. Trust what he says or risk great bodily harm.
Aside from the window dressing, functionally there isn't one thing on that bike worth copying. If you started over from scratch and built it with the same "look" but did everything the right way instead of cutting corners it might be fun to ride.
The raked triples on that disaster prolly cost more than the whole bike. Cutting and welding the neck correctly would probably have cost 1/10 the price of doing it the wrong way.
Those who don't know their history are destined to repeat it. A lotta dead guys from my generation and before led to such "accessories" as raked trees, slugs, and spools, falling out of fashion. The overleveraged rigid swingarm is a more modern twist. Do your homework. Build cool, but build right.
Sorry for hijack AND the rant, Catamount. Lotta good builders over there.
