Another little gap
Packaging takes up so much time! This tube has to go here, otherwise some other tube will foul the clutch throw out lever, or the starter motor drive. And Rotax had to put their cam drive pulley there too.
What's worse is that this gap directly adds to wheelbase. Still, it's a lot easier slotting this motor into a track FF than that old Reliant-Moto Guzzi combo. This'll be lighter, stiffer and lower, just not shorter.
