I believe scotto is correct. I have the GT-2 with a Starfire Gen II on
this bicycle and it fits nice and low, and just right above the chrome
chaingaurd. The bicycle right out of the packing box had me concerned
a little bit because the HD rear set=up was hard to turn the wheel around
in circles by hand. After I peddled the bike around the block, it loosened up
quite nicely and turned freely. My opion of this bicycle is that it is a great
bicycle to motorized and I peedle real slow on start up of the engine which
I just love.
