We are talking about a 384 pound sport bike NOT four heavy huffy bicycles! Keep in mind that a rack that will hold a sport bike is going to have the big part of the weight pushed outa decent amount so that the fairing and clips will clear the back door... if you ask me, thats gonna be a decent distance... I have jacked my VX by the hitch too... works fine for short time with a fairly static load... but if you put the dynamic load of a 384 pound bike, probably centered at least 12-15" from the mounting surface of the frame, you have a HUGE force... are there any engineers here? I'm sure there are plenty of formulas to calculate this... and again... there is a HUGE difference between some bicycles and a dang sport bike... aka MOTORCYCLE... just my 2 cents.

TTYL!
