[The top two Pro-class entrants, both the AGNI and XXL teams, relied on an existing streetbike chassis (a late-model GSX-R600 for AGNI, and a late nineties Laverda Formula for XXL), compared to the Mission and MotoCzysz machines that were purpose-built from the ground-up. The third-place Brammo machines were highly modified versions of that company’s existing Inertia production bikes. Given the speeds that these machines were navigating the course at, however, chassis technology was not a limiting factor, nor was rider skill. The limiting factor at this point appears to be available battery and electric engine technology. The MotoCzysz, which reportedly produces 150 lbs.-ft. of torque, simply melted its (three) motors. Others teams that chose a lower-power, lighter-weight strategy to get them over the mountain suffered different problems, running out of juice crossing Snaefell Mountain. The lighter-weight, moderately powerful Brammo split the difference, with mixed results. One of Brammo’s two bikes suffered motor failure 11 miles in at Cronk-y-Voddy. The other machine finished in the last spot on the podium but just barely, eating its motor in the process too.
