Is it true that they don't even have grease fittings on there a arms. If so long term reliability would suck.

Overheating: heat transfer problem.
Engine RPM's: F=ma. To simplify use the con-rod and piston as your mass. Figure out acceleration based on stroke and RPM. Remember at bottom dead center and top dead center your piston is moving at 0 meters/second. In between it's moving awfully fast.
Engine RPM's: a cyclical fatigue problem. Increased forces for a longer duration in time = an increased chance of failure.
Rev Boxes: I answered this because I asked that same question back in 2002. If you really want I can post some notes about gearing, power output and power required.
Grease Fittings: Just look at the parts! These are ATV's, not cars. Disassembly fairly simple.
