It seems only fitting that after reviewing the BRD RedShift SM prototype, that we should turn our attentions to another prototype machine…or should we say, a prototype of a prototype. A glimpse into how lost in the woods Yamaha was with its MotoGP program pre-Rossi, the 2003 Yamaha YZR-M1 prototype is the work of a company desperately looking for a solution against Honda’s very potent RC211V. Employing two Öhlins rear shock absorbers, Yamaha’s philosophy and process of handling over power is very evident in this prototype’s design, though the implementation seems a bit murkier.
Laced with linear potentiometers through out the M1’s chassis, it is at least interesting to note the unit extending from one of the rear shock mounting points to the front of the frame — presumably measuring the flex of the chassis from front to back. With all the data acquisition that is on the 2003 prototype M1, you would think Yamaha would notice one of the most obvious mistakes with the design, namely how the exhaust routing was cramped in with both shock absorbers, surely cooking both units as the machine came up to temperature.
