Overloading a sportbike?

Question

what will happen if I overload a 500cc sportbike by 80 pounds every so often.

Answer 1

Try to avoid speed bumps and potholes.

Or go on a diet and get a lighter girlfriend.

Check the tire inflation recommendations for your motorcycle, and inflate appropriately for the higher load.

Answer 2

Try adjust the shock to the hardest position and replace the forks oil with a heavier grade fork oil.  Get a bigger bike!

Answer 3

you will wear out the rear shock faster

Answer 4

well more weight creates more wear on all the drive components so it will just break the bike faster.
