Behold the largest stock streetbike transmission made.

Extra wide distance between shafts allows for the largest transmission in a streetbike.

A good shot of how wide the gears are in this 6 speed.

Input shaft

This is the input bearing carrier on the right side of the cases where the clutch push-rod shaft goes through.

A extra large clutch, like those found on a Z1, KZ or the later ZX11.

Can you say "Overkill"?

Wider means bigger gears, bigger gears means larger teeth (I'm halfway temped to try a stock gear box).
