The theoretical critical rpm (for a single cylinder engine) is dependent upon the rod length to stroke ratio (as Bill alluded to) as this takes into account piston acceleration, but I can't find the formula.
Practical limitations have changed over the years. In the 50's, bearing technology was the major limitation, but nowadays definitely rod bolts (for us mere mortals anyway). Valve actuation and control was a major issue for F1 manufacturers as they pushed their limits.
