Vertical head pipe support positions upper and lower arms to increase suspension rigidity while suppressing head pipe periphery size.
Rotating linkages maintain a substantially linear axis of compression for air springs, resolving shock absorption limitations in trike rear axle assemblies.
A leaning vehicle steering mechanism uses a deformation transmitter to transmit rotational force between the body and front wheels.
A rocking controller uses a drive shaft penetrating an arc-shaped lock plate to position the motor behind the mechanism.
