Section 6 – Front wheels, Fork & Steering
GENERAL
Three wheel models utilize a suspension mount front fork or a
non-suspension front fork. Both can be coupled with either a
loop tiller control bar, a handle control bar or steering wheel with
a rack and pinion steering assembly.
Four wheel models are operated by a loop tiller control bar, a
handle control bar or steering wheel, connected to the rack and
pinion steering assembly.
The rack and pinion assembly pushes and pulls on tie rod ends
to control front wheel steering.
