I have searched and called all the NAME makers,  gen mar, rox, etc, but no one has any YET.. So I took the way on here called the poor mans risers ,,   1 inch tall chrome spacers  with longer chrome bolts.. IT will do until someone comes out with real pull backs

I would really like mine about 1/2" to 3/4" further back.  I don't mind the height.

Due to the angle of the top triple tree, bringing the bars up will also bring them back. Not sure how far.

The Rake angle on the Trophy is 27 Degrees.

If you add spacers underneath the Handlebars, you are increasing the length along that angle.

This will have an effect on the actual "Vertical" height, and the amount that the Bars are Pulled Back.

For every 1 unit of extra length along the Rake angle,
the "Pull Back" will be approximately 0.45 Units, and
the vertical height will be increased by approximately 0.89 Units.

Using Pythagoras' Theory you can calculate the length of spacer needed to achieve the desired results.

Examples :

If you wanted a Vertical height increase of 1 inch, ( or cm )
the Spacer would need to be approximately 1.12 inches ( or cm ),
and this would give a Pull Back of 0.51 inches ( or cm ).

If you wanted a Pull Back of 1 inch ( or cm ),
the Spacer would need to be approximately 2.22 inches ( or cm ),
and this would give a vertical height increase of 1.96 inches ( or cm ).

There's a useful calculator "on-line" here if required : Right Angled Triangle Calculator

The accompanying diagram should help further explain  :028:
