These frames were originally designed by US Choppers for their unique ‘Boardtrack Platform’ project. The single cradle design and low-slung weight permits incredible lean angles. And having the motor weight pushed forward, enables aggressive riding into corners, while the centered drivetrain gives perfect balance and lean symetry. These frames will accomodate any pre-Twin Cam Harley-style engine up to 124 cubic inches including Indian PowerPlus engines, and rear tires from 160x16" to 90/90x21". There are two versions available.... one with a curved backbone that requires a custom curved gas tank, and one with a straight backbone that is intended for use with our new Paughco 1915-style tank.
Note: Frames are build to order with an expected ship time of 4 - 6 weeks. A Paughco Tech will be in contact over the phone to verify build specs.
