Straight bars

Sounds like the Speedmaster bars might suit. They are straighter and further forward. I road tested an America before I bought my Speedmaster the America made me feel rather silly and limp wristed.

 

Harley bars will fit the America as it shares it's 1" bars with the Bonneville (though not the style of bar).
I had Harley bars on my Bonneville for a while.

 

Hi MrOrange, have you tried adjusting your existing bars to make them more to your liking? If you haven't, here's a "How to.............."

1. Slacken but do not remove the 4 central riser bolts that hold the bars in position;

2. You should now be able to rotate the complete handlebars forwards by an amount to suit your needs. I would go with 1 inch increments; then do a test sit. DO NOT WORRY ABOUT THE HANDLEBAR CONTROL POSITIONS AT THIS STAGE - that will be dealt with later once you've found the position you like.

3. You'll notice that by rotating the bars forward, you also change the angle of your wrists.

4. If you need to change the angle at your wrists, you can do this by putting the 'bars in a vice and using a stout bar or a ratchet strap apply consistent pressure the end 8" on the 'bar and bend them forward.

5. Now that you have the 'bars how you want them, refit the 'bar controls to taste. You may need to file down the little plastic locating pin on the RHS control.
