The WHE-25 is designed with six connecting rods sharing one crankpin on the crankshaft . The standard design for such connection is with a degree of freedom, i . e ., the spider bearing itself can rotate in one direction until its motion is stopped by impacting with the connecting rods, then rotate in the other direction through some angle before it is stopped by again impacting connecting rods.

On February 1, 1994, the company filed its application with the following description : " The mark consists of the exhaust sound of applicant's motorcycles, produced by V-twin, common crankpin motorcycle engines when the goods are in use . " Nine of Harley-Davidson's competitors filed oppositions against the application, arguing that cruiser-style motorcycles of various brands use the same crankpin V-twin engine which produces the same sound.

To reduce the length of the engine further, by one-half a cylinder diameter, the two banks of 6 cylinders of the V-12 were not offset the " big ends " of the connecting rods of each cylinder pair in the " V " where they mated with the crankpin were thus at the same spot with respect to the engine block's length rather than offset; this required a " fork and blade " matched pair of conrods for each transversely oriented pair of cylinders.
