Well I own a 2003 speedmaster and a 2001 sportster 1200 S. My speedmaster Dyno'd at 62 rear wheel hp, I forgot the torque. That was with air box removed and carb adjustments and pipes. My harley specs were 61 hp and 65 torque with only pipes and rejetting. This the S model with 4 spark plugs, 2 per head. They are a pretty close match. I enjoy both bikes for different reasons.
Outer banks your wifes bike is a beauty and im sure she'll enjoy it.
