TWISTGRIP CONTRO
rw0
types o f twistgrip are employed, one hav~ng the normal quick action and t h e
(which
i s
fitted t o the TR5 only), a progressive action which gives t h e com-
r i d e r more t h r o t t l e control at l o w speeds. I n each case t h e damping of
[he r o t o r is controlled by a knurled adjuster n u t fitted i n t h e twistgrip. To increase
[he damping, screw i n t h e adjuster until t h e friction is sufficient t o hold t h e r o t o r
i n any position. Remember that the twistgrip w i l l close immediately t h e
hand
is
removed t o give a road signal i f t h e damping device is n o t sufficiently adjusted.
Maintenance
