I don't think there is a chance anyone can afford to manufacture cranks to stroke the crossfire, a bigger bore is much cheaper way to make c.c's and you get to rev a little higher than a stroked motor with stock cranks.

Don't get me wrong I would totally jump on a stroker crank if they where offered here in the states for $2,000, but a $10,000 crank just doesn't do it for me.
