What is the curb weight of a Harley Davidson sportster 883 low 2005 max weight of bike and rider?

Heh, kerb. ANSWER: Since I'm assuming you meant "curb" weight, your bike with out rider weighs approximantly 550 pounds. Max safe loaded weight is approximantly 1100 pounds. That is, the total of bike and rider and load. That doesn't mean you can safely load 1100 pounds on your bike but rather about 550 more pounds.
