+ 1 on what Chy said.
A couple of things I would mention, tire pressure. Make sure they are properly inflated. A lot depends on preference, riders weight and the tire itself. I would suggest in the range of 33-38 front, 35-40 rear.Play with the pressure till you find what works for you.
Additionally proper gear selection is essential. for instance you would not want to come into a tight 20mph curve in 5th gear.
The America is a truly amazing bike and in due time you will be able to drag all the bits off her in the twisties.
Oh yeah, welcome to the forum


It's not speeding till you get pulled over.
