ZZZZZ2 Departure to ZZZZZ at 4;000 feet.  Max airspeed at ZZZZZ1 230 kts; restriction loaded in FMS and briefed. Light aircraft with high climb performance; PF became concerned FD and AT commands would cause difficult level off.  Lowered pitch below FD command bar to correct which resulted in acceleration; PF thought VNAV and AT weren't complying restriction and began to reduce thrust.  PM commanded correction to FD pitch and proper speed; but during correction speed accelerated above 230 kts to approximately 250 kts momentarily before correcting to 230 kts.  Improper pitch and power for VNAV guidance and flight conditions. Proper understanding of how VNAV modes handle restrictions and good briefing of anticipated modes and performance beforehand.
Air carrier Captain reported a speed deviation during departure.
