the manual for my 2003 gl1800 states max recomended weight for cargo and passengers is 417lbs. Which for me means by the time I and my other half and her curling irons, makeup, jewelry, extra clothes, tampons, and several cell phones are loaded, we are just 1 whopper meal short of the max.
04,03.02 or what ever Honda will give a weight limit that lets you ride 2 up and carry about one pound in baggage.
The reallity is they are keeping a way out of any lawsuites.
We have an 02 and load it with all it will carry and add a trailer loaded.
Some will say this is foolish.
The reality is the bike will carry all you can put on it and preform great.
But it is up to you to drive according to the conditions and the weight on board.
The feel of the bike and your abilities = a safe ride or disastor.
When is the last time you worried about overloading your car or SUV.
The 1800 is the same.
Weight, road conditions, weather, your abilities, all add up to the saftey factor.
