Mr. Potato Head was conceived in R&D a few years back to study the configurational possibilities of putting universal bosses on a featureless tranny case. Just like the Mr. Potato Head toy you can end up with a genetic hermaphrodite with a little off-the-menu creativity. The universal tranny case accepts an A-flange, B-flange or EVO flange. It also accepts all kinds of tail stocks. This excercise yielded the easiest solution to offsetting a tranny case side-to-side or up-and-down in short production runs.
The RT250 vision began at Rolling Thunder when they divulged plans to develop a FL-type Bagger frame that was setup for a 250 tire and Softail length primary in a balanced RSD chasis. They approached us about doing a special tranny that was specific to this frame. Mr. Potato Head technology finally found its first home and we named it the RT250 project.
