yep they are around 700grams if i remember it right.. naa not a problem been past 7500rpms many times with them and no problems this engine had corrected stock rods earlier and has been turned lots higher in the past. they may be heavy but they also wont deform or flat out break for nothing these have lived thru cracked cylinderwals,droped valves and even ben run with a serious collant loss and the pistons are still fine
