Biking Power

Do you have a passenger, about 150 pounds., In the back of a Harley really make a difference in power / bike?
Is it really affected by the addition of extra pounds on a bicycle built like a Harley or weighing 700-800 pounds. so the power of the bike? I mean well please no more nasty, infantile comments. BTW, I am the passenger and have said they do a hell of a backup!
An extra 150 pounds is a weight gain of about 20% by motorcycle so heavy and out of course will have an impact on the speed, center of gravity, air resistance, etc. and other points such as crossing will be too high, needs to adjust tire pressure, mileage, etc. How much gas reduction is 150 lbs will affect acceleration and top speed? You will have to prove this truth – that you will be surprised to see the impact of what little they have actually – but if you is a lover of HD like myself that is not one of these factors. I like the society that my Softail. If you feel the need for speed – not to buy a pig.
