BACK-BONE
This type of frame is made up of a combination of pressed
steel plate and steel tubing.
This basic frame design is used mainly on scooters and some
of Honda's earlv motorcvcle desions. Back-bone construction
allows added frkedom in the overall design of the vehicle and
relatively economical production
DIAMOND FRAME
With a diamond frame, lower section of down tube is not
connected with other frame tubes. The engine forms the final
portion of the frame structure and generates the frame strength.
The diamond frame is used mainly on small and middle-
size vehicles due t o the simplicity of its structure and its light
weight and excellent serviceability.
SINGLE CRADLE FRAME
The single cradle frame has one down tube and one main pipe
at the front of the engine. The frame structual material sur-
rounds the engine. This frame is mainly applied to off-road
vehicles and middle-sized, street sport models due t o its light
weight, durability and ease of serviceability.
DOUBLE CRADLE FRAME
The double cradle design is similarto the single cradle frame, but
has two down and main tubes, resulting in increased rigidity.
A part of the down tube can be removed to facilitate engine
removal on some models. This frame is mainly used on large
displacement street motorcycles
