All models are fitted with a tubular and
pressed steel one-piece frame.
The engine and transmission unit is linked to
the frame by a pivoting silentblock assembly at
the front and by the rear shock absorber,

Front suspension on Speedfight models is
satisfactory remedy for such damage. A few
by a monolever, single-sided leading link with a
frame specialists have the jigs and other
single, non-adjustable shock. Front suspension
equipment necessary for straightening the
on all other models is either by conventional or
frame to the required standard of accuracy,
but even then there is no simple way of
assessing to what extent the frame may have
been over stressed.
2 After a high mileage, the frame should be
examined closely for signs of cracking or
splitting at the welded joints. Loose engine
mount and suspension bolts can cause
ovaling or fracturing of the mounting points.
Minor damage can often be repaired by
specialist welding, depending on the extent
and nature of the damage.
3 Remember that a frame which is out of
alignment will cause handling problems. If
misalignment is suspected as the result of an
accident, it will be necessary to strip the
machine completely so the frame can be
thoroughly checked.
