1 General description
The Honda CG 125 utilises a frame of open diamond type,
being a composite structure of tubular construction with a
monocoque spine. The engine unit is bolted between the spine
and the downtube to form a structural part of the frame. The
front forks are of traditional telescopic design, being controlled
by hydraulic dampers. Rear suspension is provided by a swing-
ing arm fork, pivoting on replaceable bushes, and controlled by
adjustable, hydraulically damped, suspension units.
