design analysis • emphasizes horizontal lines • smooth curves, fewer edges • exposed mechanics • low and long • stripped down to the basics, no superfluous body work

riding position 20


I analyzed the riding position of motorcycles that are currently on the market to determine proportion, scale, and sizing


testing I then made a jig that I could adjust in order to test and finalize the riding position of the Brute.
