I'd suppose even an aluminum front pulley would outlast an aluminum sprocket, due to the softer material used for the belt compared to a chain drive.
wouldn't last five minutes against the shaft splines.

I was thinking about that...
I hear the latest Aluminum alloys are pretty tough, like the ones used in airplanes and sprockets...
If the sprocket has 2 mounting screws, the seating might be even tougher.
How about anodized aluminum, with an outward layer of hard steel or chromium or something?
Or, how about an aluminum pulley with a patterned steel shaft inserted (pressed in hydraulically)?
Just a few examples of possible solutions..
Also I would pay up front to have mine made. If it's excellent quality, $50 is a good price. Perhaps $30 if it's being mass produced.
More profit could be made if they're sold with adapters for the Kawasaki bike as well....
Do they make a 24t, or only 25t?
