Before we go into detailed design for the actual Morph 4 prototype, I asked Alan to check the key dimensions of Morph 4 against those for Morph 2. Everything looks good in the drawing above.Trail in Low Rider: 2.5" (okay, a bit more trail than Morph 2's 1.3")
Trail in High Rider: -1.3" (same as Morph 2) Wheelbase High Rider: 42.46 inches (1/2" more than Morph 2)
Wheelbase Low Rider: 59.37 inches (3/4" more than Morph 2) Height to seat joint, low rider: 9.83 inches vs 12.03 Morph 2
Height to seat joint, high rider: 23.67 inches (.4 inches higher than Morph 2)
Seat height delta: 13.84 inches (2.63 more than Morph 2...very important for low CG in low rider)
Eye height delta: 16.21 inches (extra is due to change in seat back tilt?)
These are the measurements for Morph 2. Note that Morph 2 doesn't have the automatic seat adjustment system, and that it doesn't come down as far.All of these dimensions and angles look good. Nice drawings, Alan. Very clear and simple.
